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?
