normally the lockfiles aren't there, it's just now when qrunner won't
actually complete successfully.

I commented it out, 'cos qrunner wouldn't run successfully, so I was
running it manually while trying to debug, otherwise I just get loads of
logs saying that it couldn't get lockfile.

thanks :)

The date has never been a problem. I double-checked and ntp is running
fine. ntp hardly ever corrects the date, it's normally pretty spot-on.

the smtp-error log (mailman)

I actually fixed the problem (very) late last night, will detail down
below, thanks :)

thanks. What I failed to mention was - it's FreeBSD --STABLE.
I managed to fix the problem. I was checking my postfix logs, and saw that
I kept on getting timeouts while connecting from localhost, and it was
showing the email address that it was trying to deliver to. I nuked all
messages in the mailman queue with that email address. This is where I was
stumped, 'cos then it just started timing out on another address. As a
desperate measure, I nuked all mailman messages with that email address
aswell, and hey presto, it started working.
So for now the problem is gone, I still need to try and track down whether
the problem lay with postfix (more than likely) or mailman. Any idea what
all those errors were ? (the extract from the 'error' file that I pasted
which was so lengthy).
Thanks for the reply :)
