there could be clients still connected from Nov 25 & Nov 27. impossible to
tell just from a ps listing. you can use netstat and lsof to see which
processes have active connections (or are listening) on the imap port. see
the man pages for details.
but i wouldn't bother. uw-imapd is junk, and its problems are pretty much
unfixable. that explains a lot. i'd just replace it with something sane.
BTW, you chose the more difficult path. instead of just replacing uw-imapd
with dovecot, which would have been a simple action with one isolated effect
(changing the imap daemon), you chose to replace inetd with xinetd, which
affects dozens or possibly hundreds of unrelated inet daemons. why?
