Hello,
A while back I encountered a strange problem with Mailman, which we
eventually got resolved, but I don't know why. Although Mailman is working
fine now I'm still wondering what the real nature of the problem was and
I'm hoping that some of the Mailman experts on this list might be able to
provide some insight.
We had already been running Mailman on our Sun for several months without
any difficulties. Then, we had an unexpected power outage in our
building. The Sun that was running the Mailman server lost power
unexpectedly. When it came back up, Mailman would no longer send out
mail. All attempts to send mail to mailing lists through Mailman resulted
in the sendmail error message "name or service not known" showing up in the
smtp error log file. However I was able to send messages directly through
sendmail, so I know that sendmail was working properly. I talked to a
Mailman expert who suggested looking at the my mm_cfg.py file. The only
statement that I had in there was a LOCALHOST statement, with the IP
address of the local host, i.e. the Mailman server. My correspondent the
Mailman expert recommended deleting this statement from the mm_cfg.py, so I
did, and then Mailman started working again! But what's very puzzling is
that Mailman was working for us for a long time with this LOCALHOST
statement in there, and we didn't have any problems with it. So why is it
that this LOCALHOST statement was not causing a problem for us before the
power outage but DID cause a problem after the power outage? Anyone have
any thoughts on this?
Thanks very much,
Eric
