Then that wasn't the problem.

If the files are 755, that's OK, but they aren't executable so they
really should be 644.

And yes, the contents of archives/public are symlinks (the permissions
of which are irrelevant). That's so archives can be changed from
public to private and vice versa by just removing/creating symlinks.

Yes, that's why I said "(was)". However, if CommandRunner is now 2773,
it is likely that 2771 is another runner and was at the time. In any
case, 2771 was the pid of the process that tried to create the lock.

I asked, because I don't believe that the

IOError: [Errno 13] Permission denied:

error came from your 'help' command mailed to -request. In any case,
where did this error come from?. If it is in Mailman's error log,
there should also be a traceback. What is that?
