Outlook will try every second, under some conditions!

Funny, I was thinking Outlook Express for this imap problem.  I've seen
it start a new imap login to see whether there's new mail in the inbox
it already has open (this is horrible in U Wash imap, where the new
session kills the older one).  If these were evenly timed, like every
5 minutes, I would have said Outlook Express.  But these are at irregular
intervals, so I think it's something else.
