IMAP and outlook 5$!&85!!

[Bradley J. Bartram]

This may not help but I figure I'll offer it up to you anyway.

Outlook and Outlook Express as clients have non-RFC compliant methods for 
handling the IMAP protocol.  Most of the main IMAP servers choke (or make 
Outlook or OE choke).  Pretty much from my reading on this subject, the 
maintainers are all pretty much in agreement that MS should fix their 
problems.

Here are two things you might want to try.  Try running in Daemon mode as 
opposed to being spawned from xinetd (which you didn't specify but sounds 
like you are).  Xinet, as you are probably already aware, is not incredibly 
efficient when handling high volume of connections.  It also gives you a 
second point of failure and more importantly, security issues. ;-)

Have you checked out Courier Imap?  It natively handles Maildir and in Daemon 
mode is solid.  I'm currently running about 150 - 300 connections per minute 
without any problem and this is on mostly Outlook and OE clients.  Courier 
also has a smaller resource footprint than WU.

Just my $.02
