Basically, what's the best way to make sure postfix, dovecot, mutt, pine, etc., all share locks properly without otherwising comprimising system security? (Other than switching to maildir style boxes, which I'm not quite ready to do).
Why not ensure that mutt and pine access mail via dovecot's IMAP interface, and let (only) dovecot worry about locking? We use Postfix + Dovecot + a variety of mail clients without problem, but all the MUAs speak IMAP to Dovecot.
