Well, I don't know if documenting it there would actually help many
people. Users having this problem aren't trying to share mailboxes, so
they probably wouldn't be looking into that page. This is anyway
mbox-specific problem, so I added it now to mbox page:

I think it's safer to let user to scratch their head than to
automatically go change permissions in a way that might make things
I guess what I could do is add a wiki link to that error message
explaining it. How about this now:
imap(tss): Error: fchown(/home/tss/mail/.imap/INBOX/dovecot.index.log.newlock, group=8(mail)) failed: Operation not permitted (egid=1000(tss), group based on /var/mail/tss - see http://wiki2.dovecot.org/Errors/NoPerm)
