HELP: Postfix SMTP only seems to run for localhost

I recently upgraded my server to Mandrake 9.2 and I'm having a HELL of a time getting Postfix to work like it did on my 8.1 install:

SMTP refuses any connections except from localhost. My Shorewall settings aren't the problem: /var/log/messages says ACCEPT for both INPUT and OUTPUT. And, even if I shutdown Shorewall, I still get a "connection refused" response when I try to telnet to port 25 from a remote address. Telnetting to localhost 25 works.

netstat -lnt reports the following:
tcp 0 0* LISTEN

So, it looks like SMTP is bound (right term?) to localhost ONLY. How can I change this?

cause: mynetworks parameter in Postfix incorrectly configured.

Postfix is a wonderful server, but its documentation is... dense. Thankfully, "Postfix: The Definitive Guide" is quite a good book.
