Argh... yes, use Maildir, have procmail deliver locally, drop qpopper
for courierpop, qmail's pop server, or any of the other Mailbox-aware
servers. You'll have a lot less trouble in the long run IMHO. The
changeover isn't really that painful either.
Been a while since I dealt with qpopper, but wasn't the lock actually
/var/spool/pop/<user>.pop (the temporary copy of the user's mailbox)?
If that's correct, mount /var/spool on a different partition from
/var/mail, and only enable quotas on /var/mail. If you've got any load
on the server, you'll want /var/spool, /var/log, and /var/mail on
seperate drives for performance anyhow.
