I've installed Zimbra FC4 on FC4 on a machine that sits behind a firewall.
I can relay email outside. I can send/receive email on my "inside" class C LAN.
I can forward "outside" smtp traffic through the firewall to "zimbra" machine, but
postfix rejects the connections. The machine is multihomed (2 different IPs).


1) /var/log/zimba doesn't log unsuccessful smtp requests (?). How do I "up" the logging?

2) The admin guide says don't change main.cf directly, but not all postfix commands are
available through the UI. How can I edit main.cf directly?

Suggestion: add the zimbra version number and the component version numbers to the web console. Make it easier to ask questions.

Nice work on the product. Good luck in the marketplace.
