DISABLING ETRN SUPPORT
ETRN support specifies that the machine's FQDN will be conveyed to all remote SMTP hosts when Internet Exchange is sending
out mail. This screen displays the connection profile parameters and allows you to disable ETRN support.
To disable the ETRN support, do the following steps:
- Configure the following parameters:
- Send keep alive packets
Sends periodic data to the discard port of the remote system to keep the link active (typically used on PPP or some
ISDN connections). Some TCP/IP stacks can be configured to time out and automatically disconnect after a predetermined
period of zero network activity. Under this condition, it is necessary for the system to keep the stack active if SMTPD
is to continue receiving incoming mail. This option enables SMTPD to keep sending alive packets to maintain the dialup
connection.
- Run a program when connection is established
Allows the administrator to define the path of the program to be run after the connection is made.
- Click the Apply button to save the settings.
