ENABLE/DISABLE ETRN SUPPORT
This page allows you to configure the different aspects of the Connection Profile.
If the "Enable ETRN Support" appears on your screen, it means that you are to configure the parameters of the "Disable ETRN Support". If the "Disable ETRN Support" appears on your screen, you are to configure the parameters of the "Enable ETRN Support".
1. Click on "Alternate Name List" to enable the gateway to send ETRN requests
that specify its alternate name list to all the remote SMTP hosts.
2. Enable the "Send ETRN". Sometimes it might be useful to enable sending an ETRN request only to a specific host to which there might not be any outbound mail. This ensures that even though there is no outbound mail to that host when SMTPC runs, the host still receives ETRN requests.
An option to "add/delete" hostnames is also available. To add a hostname, enter the hostname and click on the Add button. To remove a particular hostname from the list, select an entry from the list and click on the Delete button.
3. Click on "Send keep alive packets". For TCP connections established over a dialup connection (typically 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 gateway to keep the stack active if SMTPD is to continue receiving incoming mails. This option enables SMTPD to keep sending alive packets to maintain the dialup connection.
4. Click on "Run a program when connection is established". This option also allows the administrator to define the path of the program to be run after the connection is made. Extra parameters regarding this function can be entered in the next section.
To immediately implement the settings click on the Apply button. To discard the changes click on the Reset button.
