IMAP and outlook 5$!&85!!

[Robert Meyer]

Well, Justin, you win the prize.  It was a combination of xinetd instances
being set for 60 and stupid Outlook initiating sometimes as many as 10 or
12 simultaneous connections to the IMAP server.  It turns out that there
is mention of this behavior on one of the University of Washington's web
pages.  I set the number of instances to 'UNLIMITED' and it looks like it
wants to hang out between 80 and 110 sessions alive at any one time.

I mentioned Cyrus IMAP, when I actually meant Courier IMAP.  I tried that
after it became aparent that these folks needed to have folders with sub
folders and messages in them.  'mbox' format doesn't support that kind of
thing, 'cuz mbox uses one file for all messages and you can't stick a
directory in a file.  I tried Courier IMAP but kept getting messages to
the effect that outlook couldn't synchronize with new messages.  I checked
the courier site for information and he mentioned that outlook had problems
and he wasn't inclined to do anything about it.

Insanity prevails...

Cheers!
