I'm new to this forum; when I went Googling for solutions to these two minor problems, though I didn't find an answer here, it did look like a good resource.

I have a 7600 with a 400MHz Sonnet G4 upgrade card and 1 gig of memory that runs desktop OS X 10.4. On it I am running the stock BIND, Postfix and Mailman. I use Webmin to administer BIND and Postfix.

There are two small problems with the installation:

*Postfix is taking on the default hostname from the "Sharing" preference panel (as in abcd.computer.local). This causes only the small problem that the default addresses for Mailman (mailman-bounces, mailman) are set to abcd.computer.local rather than the DNS name of the machine, which means those pieces of mail don't get delivered. Where in the Postfix config file can the default hostname be changed from the preference panel name?

*On an infrequent basis, Postfix just rolls over and dies. Sometimes it's two or three times a day, sometimes it will go for a week without happening. This installation had been running on OS X 10.3 and the upgrade was not an easy one.

Here is what the log says when Postfix dies:

Aug 14 08:02:09 machine-name launchd: org.postfix.master: exited with exit code: 1
Aug 14 08:02:09 machine-name launchd: org.postfix.master: respawning too quickly! throttling
Aug 14 08:02:09 machine-name launchd: org.postfix.master: too many failures in succession

Any thoughts or comments would be appreciated.
