DISABLE ETRN SUPPORT
This page allows you to disable ETRN support.

1. Tick the Send keep alive packets for TCP to establish a dial-up connection (typically PPP or some ISDN connections). Some TCP/IP stacks can be configured to time out and automatically disconnect after a pre-determined period of zero network activity. Under this condition, it is necessary for the gateway to keep the stack active if you want the SMTPD to continuously receive incoming mail. This option enables the SMTPD to keep sending alive packets to maintain the dial-up connection.

2. Tick the check box of the Run a program when connection is established. This option also allows the system administrator to define the path of the program to be run after the connection is made.

3. Click the Apply button to immediately implement the settings. Click the Reset button to discard the changes.

NOTE: Clicking the Enable ETRN Support button will display another screen where you can enable ETRN support.
