Environment
Novell GroupWise 7 Support Pack 1
Novell GroupWise Internet Agent (GWIA)
Situation
When installing GWIA on a Linux server, if the native SMTP server is disabled, applications that use these services will fail to send successfully. Examples of these applications are mutt, mail and also OS processes that send logs and alerts to root or other users.
Resolution
The native SMTP server (Sendmail, Postfix, exim) needs to be
configured to use GWIA as the outbound relay. For this to be
successful the GroupWise system must be at version 7.0 or later.
Then be sure to bind GWIA to the IP address of the server in the
ConsoleOne GWIA properties Network Address page.
Next configure the SMTP server to only listen on the loopback
address of 127.0.0.1, which is the default Postfix configuration.
This option is inet_interfaces in the /etc/postfix/main.cf file. A
properly configured line in main.cf would appear as:
"inet_interfaces = 127.0.0.1".
To set Postfix to relay all outbound mail to GWIA, add, or
edit, the relayhost line, also in /etc/postfix/main.cf, to relay to
GWIA. As GWIA and Postfix are on the same server, you should
configure this line to use GWIA's bound IP address. This line
should read "relayhost = [10.0.0.34]" (square brackets are required
when using an IP address).
Then reload Postfix using the command "/etc/init.d/postfix
reload"
For other Linux mailers, refer to their documentation on how
to configure the same options listed above.
