Internet Exchange for cc:Mail Version 2.1 Release Notes Version 2.0
represents a significant advancement over the previous version 1.04b. Several new features
have been added, including the following: Macintosh File Handling Extensive Macintosh file handling support
has been added, including support for the MacMIME standard and BinHex. Rules Based Addressing Flexible new address management between
cc:Mail user names and Internet addresses allows the gateway administrator to select their
own address translations between the two formats. This results in significant time savings
over conventional manually maintained address translation tables. Multilingual support has also been added on
the ccmailName<=>InetName mapping. The administrator can now define extended ASCII
code mapping. Peer Based Encoding Methods Internet Exchange now allows the gateway
administrator define the capabilities of remote systems, including the attachment types
that each site can decode. Before a message is sent, Internet Exchange determines
the appropriate attachment types and encoding methods based on what the remote system
supports. Administrator Specified Usage Control Internet Exchange allows the
administrator to establish "permissions" related to communication with remote
sites and local users. It is possible to disallow the sending and/or receiving of messages
between your site and another. In addition Internet Exchange will check for
permission to send Internet mail for each local cc:Mail user that sends mail through the
gateway. Improved Security Security protections include anti-spoofing,
SMTP port reassignment, remote host restrictions (inbound), and local user restrictions
(inbound). Database Backend A database backend engine has been added to provide fast
capabilities lookup compared to common text based approaches. The new databases include the following: Name Database File Backup Text File Alias Database smtpadr.btr smtp.adr Domain Database smtppod.btr smtp.pod Directory Database rulebadr.btr - none - Magic Database magic.btr [magic] in ima.ini DNS Cache dns.btr - none - Message Database mesg.btr - none - Peer Database peer.btr - none - When upgrading from Version 1.04x, the
installation procedure will automatically startup the conversion utilities that create the
initial database files. In addition, where backup text files are specified, it is possible
through Auto Conversion to externally maintain this information in these text files, and Internet
Exchange will detect if and when changes are made and automatically updatethe internal
database files. DNS Caching The Domain Name System (DNS) system has
been upgraded to include a local cache, reducing DNS traffic for repeat connections. This
has the effect of significantly reducing outbound SMTP connection times for many sites. Automated Technical Support Internet Exchange now directly
supports bug reporting via Internet email to support@ima.com. This capability is
accessable from the Help button on the main SYSMAN screen. Enhanced Auto Shutdown The auto shutdown option can now specify a
time interval from when the gateway was started rather than an absolute time. The time can
be specified in the format "+hh:mm" or "+mm". Windows 95 Dialup Networking Support Added support has been added for dialup
PPP. Under Configure Schedules it is now possible for Windows 95 to specify the dialup
networking name for the remote site to contact. This will enable auto dialing and auto
shutdown of the connection under Windows 95. An external scheduler however is still
required to automate the startup of Internet Exchange. TCP Application Level Keepalives - A new
option under Configure Schedules has been added that enables the generation of single UDP
"keepalive" packets to be sent to a remote discard port. This can be useful for
keeping SMTPD alive during periods of inactivity on a dialup connection. Renaming of admin.exe The Internet Exchange System Manager
has been renamed from admin.exe to sysman.exe to avoid confusion with the
similarly named cc:Mail utility. Audible Warnings Audible warnings (beeps) have been added when any of the
monitored resources reach a critical level. VERSION 2.01 CHANGES Non-deletion of bounces When CCOUT decided to bounce an outbound
message back to its cc:Mail originator (usually due do an invalid recipient address) it
did it correctly, but failed to delete it from the post office. This resulted in a
ever-growing set of copies of the same bounce being sent to the originator, until the
offending message was manually removed through the Sysman interface. Wrong mapping of cc:Mail addresses containing special characters The default mapping of cc:Mail user names
containing characters invalid as RFC822 address local parts outside quoted strings (such
as '@') was mis-handled, with the addition of an extra double quote. Malformed BinHex'd files causing GPF in CCIN CCIN crashed attempting to convert corrupted BinHex'd
attachments. Case sensitivity in Domain Conversion utility Due to a case mismatching, searching the domain database
for PO names did not work. Tab expansion could not be disabled A value of zero for the Tab Expansion option (that disables
the expansion altogether) was rejected as invalid. Screen corruption in "Configure Users" screen when saving changes Clicking "OK" and
subsequently "Yes" in the users configuration screen resulted
in the display being corrupted. The changes were properly saved
however. Enhancements Optional suppression of audible warnings Users annoyed by beeps and other audible diagnostics may
now turn these off by setting the following option in IMA.INI: [Options] DisableAudibleWarning=YES Elimination/relocation of superfluous or obscure log messages Some misleading messages have been removed, re-phrased or
moved to diagnostic level logging. More tolerant syntax for SMTP.ADR The conversion utility from SMTP.ADR to
Alias database used to reject lines with extra spaces between the various fields. These
spaces are now ignored. TZ variable warning message now only displayed when required If the timezone listbox entry "Use
system TZ variable" was selected, a message warning about the need of setting the TZ
environment variable was always displayed at startup, even when that variable in fact was
properly set. This message is now only displayed if the environment TZ variable is not
set. Subject of message to technical support now containing Serial Number The "Help!" subject line has been changed into
"Help! [S/N : nnnn]" Postmaster is now a mappable username If an incoming message is addressed to
"postmaster@some.local.domain", the gateway will attempt a mapping through the
Alias and Directory databases before using the cc:Mail address defined as POAdministrator
in the gateway's setup. That allows to assign postmaster@... addresses to administrators
of downstream post offices. VERSION 2.02 CHANGES Bug Fixes Inability to handle a large (>32) number of recipients When CCOUT tried to convert messages
addressed to more than 32 recipients, an array overflow occurred causing GPF or perennial
loops. The limit has now been removed. GDI resource leak in Sysman A small amount of GDI resources was allocated but not
released every time SYSMAN was restarted. Inability to enter autoshutdown times ranging from 23:00 to 23:59 "23" was unduly considered an invalid hour value. IEUPDATE required the use of the mouse Now it is possible to run IEUPDATE even
when a mouse is not installed, using only keyboard input. SYSMAN started the automatic dialing even when in "Configure only" mode SYSMAN will not initiate a dial-out procedure when
"Configure only" mode is selected. "Multipart/mixed" MIME types were not decoded under 8bit Content-transfer-encoding In compliance with RFC1521, "8bit" and
"binary" are now accepted as legal values for the
"Content-transfer-encoding" header on "multipart/mixed" MIME types. "Single dash" MIME boundaries were not recognized In compliance with RFC1521, boundaries made of a single
"-" character are now accepted. Occasional error when the "OK" button was pressed in "Configure Connection" Under some conditions, choosing "OK" in the "Configure Connection" screen resulted in a spurious error message. Installation or update procedure stopped when CTL3D.DLL was missing Despite the fact that the Internet Exchange
for cc:Mail distribution contains a valid CTL3D.DLL, the Install and Update programs could
not make use of it, and terminated prematurely if none was already installed. Message loops when a non-existent cc:Mail user was specified as "Bounce sender" When the username configured as
"Bounce sender" was not listed in the local PO's address book, an attempt to
bounce a message resulted in message loops, and the bounce was not properly sent back to
the author of the original message. CCOUT could not handle "username at PO" entries in the Aliases database Entries in the Aliases database whose
cc:Mail user names was followed by a PO specification were not handled in the outbound
conversions. Enhancements Customized notes to bounced messages Two new parameter can be added under [Options] in IMA.INI: RejUserToSendMsgFile=/full/path/filename.ext When present, the content of the ASCII file "/full/path/filename.ext"
will replace the default explanatory text accompanying messages bounced to users
unauthorized to send messages to the Internet. RejSendToPeerMsgFile=/full/path/filename.ext When present, the content of the ASCII file
"/full/path/filename.ext" will replace the default explanatory text accompanying
messages bounced to users who have tried to send mail to peers for which there is no
authorization to send to. Logfiles sent to postmaster but not saved on disk were all named "DDMMM000.LOG" The number is now properly incremented, even if the disk
copy of each file is deleted after mailing it. License agreement screen in evaluation version was displayed every time SYSMAN was started To avoid inconveniences in dial-up
applications, the license agreement screen is now presented only once after the
installation. The Update procedure did not back up IMA.INI Now IEUPDATE.EXE produces a IMA.BAK file containing a copy
of the previous IMA.INI . Customized "Content-transfer-encoding" parameter for outbound uuencoded MIME messages A new parameter can be added under [Options] in IMA.INI to
define the string used to indicate "uuencode" content transfer encoding: Uuencode=x-uuencode The default value is x-uue. The version 1.04b used x-uuencode. Both of
them are acceptable on incoming messages. VERSION 2.03beta1 CHANGES Bug Fixes "TO" and "CC" recipients sometimes replaced by "BCC" Under some circumstances, messages
addressed to more than one recipient had their "To:" and "Cc:" RFC822
headers unduly translated into cc:Mail "BCC" instead of, respectively.
"TO" and "CC". "Unique" filename weren't Some temporary filenames, supposedly
unique, sometimes were not such, resulting into racing conditions and a variety of I/O
errors: most commonly, the infamous "stat() failed". Duplication of message ID's The message ID's generated by SMTPD and
CCOUT depended on the time() function; with fast machines, and high volumes of traffic, an
input message and an output message could have been allocated the same ID. Most likely,
that would have produced error conditions and, quite possibly, message mix-ups. Message record locking An auxiliary database, LOCK.BTR, has been
introduced to better co-ordinate the access to the message base by different processes. It
is automatically deleted every time SYSMAN is restarted. GPF or crashes in CCIN when MIME messages contained more than 100 body parts The bug, related to memory reallocation
strategies, has been fixed increasing the limit to 300 body parts and bouncing messages
exceeding that limit. Mis-handling of return error code inside the MIME encoder This was responsible for "outch: _lwrite failed"
error messages being profusely logged. Apple "Type" and "Creator" fields wrongly converted to lowercase The content of the "Type" and
"Creator" field for Apple files in "Configure MIME" was unduly
converted to lower case before being stored in the MAGIC.BTR database. That prevented the
"Force Apple" options (both for incoming and outgoing messages) from working
correctly. Enhancements More descriptive message ID When user selects a message and press a
button like status, bounce or forward, the message ID for that message is now displayed on
the dialog box title bar. VERSION 2.03beta2 CHANGES Safer Dynamic Address Conversion Should any error occur during the address
conversion, the old aliases database will not be replaced. Instead, an error message will
be mailed to the Administrator. This should prevent the mysterious sudden disappearances
of the Aliases database reported by some users. VIMSetMessageItem NOTE_PART failed If attaching a text as cc:Mail note part fails, the
operation will be retried as text file. Duplicated ccMail Recipients under VIM6 VIM version 6 produces an error condition
when the same recipient address is present more than once. This bug has been fixed by
eliminating duplicated addresses, also, the Recipient Type will be changed under the
rules: - Whenever a recipient appears on a "TO" field, its occurrences on other recipient fields are suppressed; - Whenever a recipient appears on a
"CC" field, its occurrences on "BCC" fields are suppressed. A spurious "Cannot delete message, internal error" message popped up when the administrator tried to delete a message in either the "SMTP in" or "SMTP out" queue This bug has been fixed. Message locking for ccOut Now ccOut will insert the message ID (VIM reference number) into a locks database (lock.btr) before trying to access it. Should the insertion fail due to "already existing record", that message will not be processed and skipped. After successfully processing the message, that record will be removed from lock.btr. When sysman displays the queue status for
the CCPO, an asterisk ('*') will precede the message date if the message ID is found in
lock.btr. This indicates that the message is currently being processed by ccOut, _OR_,
this message has not been exported by ccOut due to some VIM error. In that case, the
system administrator can use the '*' to locate the bad message and delete it manually. Space in content-type parameter. Some non fully MIME-compliant mail programs generate
"Content-Type" headers like: Content-Type: application/x-zip; name = "123.zip" The space in front of and after the
"equal" sign is not valid, but, in order to accomodate those cases, we have
modified the decoder to accept that format as well. This, however, requires that
double-quotes be used to delimit the parameter. Enhancements Dial-up connections will not be closed until SMTPC has finished sending the current message This will allow to send messages whose
transmission time exceeds the scheduled connection time. The enforcement of "Permission to receive" from a peer is now based on the domain declared in the "MAIL FROM" SMTP command In previous versions, the control was over the domain
declared in the "HELO" command, that is the domain of the host involved in the
last hop. The "MAIL FROM" domain refers, more logically, to the domain of the
original sender (envelope sender). VERSION 2.03beta3
CHANGES *** IMPORTANT GPF WARNING *** The VIM library included in the version 6
of cc:Mail appears to cause GPF's and other system crashes when Applesingle attachments
are imported into the post office. Until a new version of VIM 6 fill fix this problem, the
administrators are advised to select the "Force Native" checkbox in the
"Options|Inbound Attachment Option" pane. This does not apply to installations
where VIM 2.21 is in use. Bug Fixes Sleeping SMTPD We have changed in SMTPD a socket shutdown
procedure that, under some circumstances with Windows NT 3.51, was found to prevent
successive instances of that process from accepting new connections. This should remove
the main, if not only, cause of this important malfunction. Enhancements Japanese language support From the version 2.03beta3, Internet
Exchange for cc:Mail includes Japanese language support, at the level previously available
in the separate version 2.03JB3. Besides all the points for the
corresponding English version, listed under the title "Internet Exchange for cc:Mail
- Enterprise Edition 2.0 Release Notes", the following additional notes apply: - For outbound (cc:Mail->Internet) messages, if "ISO-2022-JP" is selected in the gateway setup as local character set, the gateway assumes that all the messages in the Internet queue are encoded in a mixture of ASCII and Shift-Jis; codes higher than 128 trigger a Shift-JIS to ISO-2022-JP conversion, instead of the QP encoding used when the character set is ASCII or ISO-8859-x. NOTE. This implies that it is not possible
to export from the same Internet PO mixes of messages containing Japanese characters and
messages containing ISO-8859-x characters. The only solution for mixed Japanese/European
environments, at present, is to use two gateways serving one Internet PO's each (say,
INTERNET-I for messages whose 8-bit codes should be QP-encoded, and INTERNET-J for
messages whose 8-bit codes should be transcoded into ISO-2022-JP 7-bit JIS). - Inbound messages are converted from 7-bit
JIS to Shift-JIS if they bear the "charset=ISO-2022-JP" parameter on the
"Content-type" header; non-MIME messages will be converted only if the file
IMA.INI (in the windows directory) contains, under the [Options] paragraph, the line: ScanForJIS=YES If, in addition, the line RepairDamagedJISinNonMIME=YES is present, the gateway will attempt to
recover JIS messages without ESC characters (some mail transports, unfortunately, filter
them out). This feature uses heuristic criteria, and might produce incorrect results in
certain cases. The same result, in MIME messages, is achieved if the
option: RepairDamagedJISinMIME=YES is present. The same warning as above applies here. - Finally, invalid Shift-JIS codes can be removed from the
outbound message with the option: InvalidCharacterMark= or mapped to an arbitrary string (e.g., *INVALID*) with: InvalidCharacterMark=*INVALID* Installation for Japanese post offices The distributed kit is a self-extracting ZIP archive that, once run, will produce an installation disk (evaluation version). The installation procedures are the same as for the English version; in particular, the VIM library must be the English one, version 2.21, available from: ftp://ftp.ccmail.com/pub/comm/ccmail/dev_tools/vdlwin.zip
We haven't yet tested the Japanese version
over the VIM version 6, that is necessary for the new PO format (DB8) but is not yet
available from Lotus' ftp site (the only way to put it in place is to install a copy of
the cc:mail client for the version 6). On the other hand, the underlying version of Windows MUST
be one with Japanese language support. VERSION 2.03beta4 CHANGES Bug Fixes Memory leak in MIME library A memory leak affecting sysman, ccIn, smtpd and smtpc has
been discovered and fixed. Recipients unduly removed The code to remove duplicated recipients,
introduced with 2.03beta2 to avoid a problem with VIM 6, was sometimes removing legitimate
recipients as well. SMTP "5xx" responses during the initial greetings phase will now cause SMTPC to bounce the message Response codes starting with "5"
are to be considered permanent; however, SMTPC insisted in retrying the delivery if such
codes arrived in the initial "greetings" phase. ccIn can now handle uuencoded files with 4 digit in the headers Some rare uuencode utilities produce files starting with
lines like: Begin 0644 file1.doc Instead of the more common: Begin 644 file1.doc The four-digit format used to be considered
invalid by ccIn. Now, both formats are considered acceptable and equivalent to each other. Enhancements Check on the mail relay host domain Using the gateway's FQDN as "mail
relay host" is a common mistake for first-time users. In previous versions, it went
undetected and the gateway tried to deliver outgoing mail to itself, with predictable
consequences. New "PostmasterIsMappable" option Before the version 2.01, "postmaster" was always resolved to the cc:Mail user specified in the configuration and saved as "POAdministrator" in the [PostOffice] section of IMA.INI. That did not allow to define different
postmasters for downstream post offices mapped to separate subdomains. As this was
considered inconvenient by some users, we relaxed the limitation keeping the
"POAdministrator" parameter simply as default when no other mappings existed.
Unfortunately, this caused unexpected problems to other users. To satisfy both groups, we
have now made this behaviour dependent on a new option. Adding the line: PostmasterIsMappable=YES under the [Options] section of IMA.INI,
the "postmaster" internet username will be considered mappable through
"users configuration", as it has been since the version 2.01 . The default is
NO, as it was in precedent versions. The Install procedure no longer need stress.dll STRESS.DLL is not necessary for the INSTALL procedure, but
a reference to it, unduly linked in the code, required its presence in order to initiate
the installation. Delayed delivery notification notes now report in the "Subject" line the subject of the original message This will allow the sender to identify the message being
delayed without having to go through the RFC822 headers attached to the note. VIM error text is now included in message bounces The textual equivalent of VIM
status/extended_status numeric codes was always reported in the log file, but not in the
"non-deliverable" notes bounced back to the Internet sender. Now it is. Sanity checks on domain names user in "Peer" configuration Characters illegal in domain names, like
"&" or "_", will now be spotted if used for the strings defining
the peer domains/subdomains. Also, surrounding square brackets will be added automatically
when user enter an IP address in the domain name edit box. VERSION 2.03beta5 CHANGES Bug Fixes GetFreeFileHandles() causing file I/O errors For statistic logging purposes, all the executable programs
(SYSMAN.EXE, SMTPD.EXE, CCIN.EXE, CCOUT.EXE, and SMTPC.EXE) used to report the number of
available free handles free before terminating calling the system function
GetFreeFileHandles() provided by STRESS.DLL. For some reason, it appears that under NT
that function consume, for a short amount of time, all the free file handles available to
the 16-bit subsystem (at least, inside the same memory space) causing serious error if
another 16-bit application attempted disk I/O operations at the same time. That call has
now been removed, and the number of database and VIM errors (the latter often degenerating
into GPF's) observed in our lab tests has dropped to zero. "554 Remote protocol error" bounces traced to erroneous SMTP response code returned by SMTPD When SMTPD, due to a timeout in the data
reception, decided to abort a "DATA" phase, it returned the response code 221.
In fact, the SMTP protocol does not allow that response: the peering client (sendmail)
usually reacts bouncing the message accompanied by the status "554 Remote protocol
error". The response "221" has now been changed to the canonical
"451", which tells the remote client to retry later. Note: the default value of
5 minutes for "SMTPDTimeout" may be too small: some UNIX systems use up to 120
minutes. Bug in routine scanning non-MIME messages for ISO-2022-JP sequences Due to a coding error, scanning incoming
non-MIME messages for ISO-2022-JP escape sequences frequently caused GPF's. That part of
the code, introduced in 2.03b3 and 2.03b4, had to be disabled with the
"ScanForJIS=NO" option in order to limit the damages. This bug has now been
fixed, and the functionality may be safely restored. "Flashing CCOUT icon" syndrome Due to a bug in the code, SYSMAN, if "Synchronous
mode" was selected, started CCOUT even if the only messages queued for export were
locked as "bad". As CCOUT could not find any "good" message to export,
it terminated immediately, only to be restarted again (consuming a great deal of CPU
resources). Now SYSMAN only counts the non-locked messages. CCIN getting confused by messages with a large number of recipient headers Messages with many "To:" or
"Cc:" header recipients caused CCIN to treat them erroneously as envelope
recipients, trying to split the delivery into multiple copies. In turn, this caused an
attempt to bounce a message that failed due to the lack of an envelope sender, and the
error message "ccIn: Warning! Trying to bounce message .... with no bad
recipients" was repeatedly reported in the log file. Under some circumstances, a GPF
occurred. Now, extra "To:" or "Cc:" headers not coincident with
envelope recipient are simply ignored if reporting them as non-delivery recipients
("Sent-to" or "Sent-cc", in cc:Mail jargon) exceeds the maximum size
allowed for the cc:Mail headers. Enhancements ISO-2022-JP scanning of non-MIME messages In 2.03b3 and 2.03b4, the ScanForJIS option by default was
set to YES. This may be inconvenient for users not interested in Japanese language
support. The default han now been left YES only if the local character set is ISO-2022-JP;
otherwise, it is NO. ISO-2022-JP -> Shift-JIS conversion now optional for MIME messages Whilst the conversion for incoming
ISO-2022-JP non-MIME messages was optional, MIME messages were always converted if the
"Content-type:" header contained the parameter "charset=ISO-2022-JP".
This was highly inconvenient for installation where the gateway runs on non-Japanese
Windows: the conversion gives erroneous results, and it prevents manual decoding by the
user through stand-alone utilities. Therefore, the conversion is now subject to the new
option, under the [Options] section of IMA.INI: ConvertJISinMIME=YES As for ScanForJIS, the default is YES if the local
character set is ISO-2022-JP, NO otherwise. "Too many recipients" message moved to diagnostic logging level The message "ccIn:Too
many recipients; will deliver to others later" is not signalling
an error condition; however, it was erroneously logged at "errors
only" level, unduly alarming most administrators. It has now
been moved to "diagnostic" level. VERSION 2.03beta6 CHANGES Bug Fixes Memory leak in NT circumvented Windows NT appears to leak global memory
every time an application is started and subsequently terminated. The cumulative effect
resulted in several malfunctions, including GPF in 0001:01F5. To avoid this problem, CCIN,
CCOUT and SMTPC are no longer started and stopped; instead, after completing their job
they remain in a idle status, waiting for a wake-up signal from Sysman. Multiple dynamic conversions prevented The new mechanism of background dynamic
conversion for SMTPBTR.ADR allowed SYSMAN to start a second instance of the conversion
utility before the termination of the one in progress, if the system schedule interval was
short enough. This usually resulted in oversized SMTP.BTR, and often in database
corruption and lock-up conditions in the database engine. Now, only one copy of conversion
utility can be run at one time. SMTPCqueueRunSize limited to 50 Previous versions allowed arbitrarily large
values for this parameter, even zero which means "no limit". That resulted in
huge memory allocations when the number of messages in the SMTP OUT queue was high. As
increasing this parameter too much yields diminishing returns in terms of efficiency, its
value has been limited to 50. The sender addresses of Outbound messages were generated ignoring the domains configuration A silly bug introduced in beta5. Now fixed. UUdecode algorithm failed under rare conditions Now fixed. DNS resolver froze when it received truncated answers from the server When the size of a DNS response exceeds
1024 bytes, the server has the option of returning a truncated reply asking the client to
repeat the query over TCP instead of UDP. The code handling this was buggy, and crashed
the calling application. GPF in CCIN when the disk space was close to zero If the free space on the disk where the
QUEUE directory resided was close to zero, CCIN crashed. Now fixed. GPF in SYSMAN when clicking on status buttons not greyed out but without messages in the window With "Regular Screen Updates"
deselected, it could happen that the Message Functions buttons were not greyed out even if
no messages were in the displayed queue. Under these conditions, clicking on any of those
buttons caused a GPF. Bug in SMTPC exponential back-off algorithm If the delivery of a message failed thirty
times, the interval for subsequent retries dropped to zero. That way, some undeliverable
messages could clog the SMTP OUT queue instead of being put aside and, ultimately,
bounced. Enhancements Possibility of disabling the reverse DNS look-up The reverse DNS look-up, while useful to
spot spoofers, is sometimes harmful to the delivery throughput: this is especially true
when the IP address of the SMTP peering client has not been registered under the
IN-ADDR.ARPA domain. In that case, even DNS caching does not help, because failed queries
must not be cached. It is now possible to disable the reverse DNS look-up by adding, under
the [Options] section, the line: DisableReverseDNSLookup=YES If this option is selected, SMTPD will
assume that the domain declared in the "HELO" SMTP command may not be true, and
will record the peer's IP address in the generated "Received:" headers. Should
there be suspicion of SMTP spoofing, that IP address will provide clues about the identity
of the hacker for an off-line analysis of the messages. Possibility of saving permissions in dynamic conversion from SMTPADR.BTR to SMTP.ADR This option achieves, during the dynamic conversion, the same result as clicking the "Yes" button in the Address Conversion utility when prompted with the question "Do you want to add additional information..." after choosing to convert from database to ASCII file. To enable that feature, add under the [Dynamic Conversion] section: UseNewAddressFileFormat=YES Possibility of partially qualified addresses By default, the gateway extends addresses
containing only a hostname (like "user@host") by attaching the local domain
suffix. This may result inconvenient for use on some intranets that don't use DNS or, in
general, domainized addressing. It is now possible to prevent this from happening by
adding in IMA.INI, under the [Options] section, the line: QualifyRecipientHosts=NO Also domain literals to mail relay host Messages sent to recipient addresses
containing domain literals (like user@[1.2.3.4] ) will be subject to the same routing
rules as for normal domainized addresses (user@domain.com). Previously, they escaped
routing though the mail relay host. Change in Configure Rule-Based Addressing The functionality of the "Configure
Rules" screen has been made more intuitive, in order to ensure alignment between
saved rules and content of RULEBADR.BTR database. In particular, saving the rules will
imply their compilation into a new database; discarding the changes will preserve the
existing database as well. Content-disposition: inline In previous releases, the parameter used in
the "Content-disposition:" header was "attachment". This prevented
Eudora users from viewing the text attachments without saving them first as files. Bounces by SMTPC will contain recipient address Previously, messages bounced as
undeliverable by SMTPC did not specify the failed recipient address. VERSION 2.1 Gold Candidate
CHANGES Bug Fixes CCOUT not recognizing CCPODOWN in beta6 The new "stay idle when finished"
mechanism, introduced in beta6 for CCOUT, SMTPC and CCIN, had inadvertently resulted in
inability of CCOUT to recognize CCPODOWN. The subsequent VIM errors caused a prematire
auto-shutdown of the gateway. This has now been corrected. CCOUT not changing default encoding until restarted in beta6 For the same reason, CCOUT ignored changes to the default
encoding. SendOldLogFile() did not generate proper envelope lines in the message file The code responsible for mailing log files
was not starting the message files with the envelope lines "#F ..." and "#R
...". Normally this caused no harm, but it prevented the recovery from some abnormal
conditions, sometimes resulting in reports of failure to "bounce message with no bad
recipients" being logged. The exponential back-off algorithm was still faulty Now fixed for good. The "Deliver", "Forward" and "Bounce" button occasionally didn't work Now fixed. QualifyRecipientHosts only affected the SMTP envelope Now it also affects the RFC822 headers. Timeout on peer's response to the "QUIT" SMTP command caused SMTPC to leave a message file stranded in the OUT queue When SMTPC did not receive a "250" reply to the
"QUIT" command within the time interval specified by the SMTPCQuitTimeout
parameter (normally 5 minutes), it failed to remove the message just sent from the
QUEUE\OUT directory. However, the message database was updated, causing a discrepancy in
SYSMAN between the number of messages displayed in the SMTP OUT counter and those shown in
the message list when "SMTP OUT" was selected. Re-building the message database
created a new record for that message, resulting in a double delivery. This bug has now
been fixed. Enhancements Maximum lenght of the "Alternate host/domain names" list increased from 512 to 2048 characters This will allow a higher number of "alternate
host/domain names". Masking of mailing list names in CCOUT made optional In versions successive to the 1.04b, CCOUT removed from the
recipients list cc:Mail names starting with the "#" character. This was a
workaround to an abnormal behaviour of the cc:Mail client, that used to generate replies
to both mailing list name AND to each address obtained exploding the mailing list. Recent
versions of the client have fixed this problem; the removal by the gateway has therefore
been made optional. The administrator can control it by adding in IMA.INI, under the [Options] section, the
line: MaskccMailList=NO The default value for this option is YES. Possibility of partially qualified addresses for senders as well The similar option introduced in beta6 for recipient addresses is now available also for the sender address: by default, the gateway extends addresses
containing only a hostname (like "user@host") by attaching the local domain
suffix. This may result inconvenient for use on some intranets that don't use DNS or, in
general, domainized addressing. It is now possible to prevent this from happening by
adding in IMA.INI, under the [Options] section, the line: QualifySenderHosts=NO Change of default values for several options The default for three options has been
modified to values more suitable to most installations: RegularScreenUpdates=NO MaxDNSRecordNumber=0 DisableReverseDNSLookup=YES Message database rebuilt as startup Every time Sysman is re-started, the message database will
be re-built. DNS cache database flushed at start-up Every time Sysman is re-started, the DNS cache database
will be cleared. Ability to ignore the domain -> PO mapping on incoming messages Some sites are based on a single
"hub" PO receiving from the gateway messages originally addressed to a number of
different subdomains mapped to downstream PO's, whose users all have remote entries in the
hub PO. In that case, the normal domains mapping should be disabled (for incoming messages
only), and the gateway should consider all the mapped domains as equivalent to the FQDN.
This behaviour can be activated by adding in IMA.INI, under the [Options] section, the line: SkipPOD=YES VERSION 2.1 CHANGES Bug Fixes Attachments of bounces to cc:Mail messages sometimes failed for sizes larger than 20K In some cases, attachments
of large bounced messages were not retried as text file attachments
when too big for being attached as note parts. That caused VIM failures.
Enhancements Japanese language support extended to all Japanese versions of Microsoft Windows through Japanese VIM Now Internet Exchange for cc:Mail supports the Japanese version of VIM 2.04, that comes with the Japanese versions of cc:Mail 2. Using the Japanese VIM allows the gateway to work on Japanese Win3.1, Japanese Win95 and Japanese NT 3.51 (and, presumably, also NT 4.0). It is important to note that: - The local Post Office should be created by Japanese ADMIN - The line VIMCharSet=CP932 must be added to IMA.INI, under the [Gateway] section. Note: the Japanese VIM can be put
in place by installing, on the PC used for Internet Exchange, the Japanese version of
cc:Mail Available from Lotus. An update to some of the DLL's can be downloaded from: http://www2.lotus.co.jp/msginfo/21b2.htm Japanese language support extended to "From", "To", "Cc", and "Subject" fields Now the Shift-JIS<->ISO-2022-JP conversion also
affects the headers. Should this cause problems, it is possible to disable it by adding to
IMA.INI, under the [Options] section, the following line: DisableJISinHeaders=YES By default, the automatic recovery of ISO-2022-JP escape
sequences lacking the escape character will not be attempted. It is possible to enable
this feature by adding to IMA.INI, under the [Options] section, the following line: RepairDamagedJISinHeaders=YES Message database ONLY OPTIONALLY rebuilt as startup Rebuilding the message database every time Sysman is
re-started can create serious problems, especially in dial-up applications. The operation
has now been conditioned to an option, by default set to NO: under the [Options] section, the
line: AutoRecovery=YES will enable the automatic recovery of the message database
at startup. DNS cache ONLY OPTIONALLY rebuilt as startup Same as above, but with default YES. To disable the
feature, put under the [Options] section the line: ClearDNSCacheWhenRestart=NO |
