Perhaps if I reword my problem this way people might know what I'm
on about!
Has anyone a dummy's guide to configuring Outlook, and Outlook
Express, as clients
to an Courier server? In particular, the settings fior Home Direcory
etc. on
the IMAP tab.
Are there any settings on the server to look out for or modify?
I think I found the answer to a very similar problem.
We have a T1 line. The mail server has it's own IP address in our
range and our LAN is on another IP. Basically, all traffic from our
LAN comes from the same IP. There is a setting in the imapd
configuration, /usr/lib/courier-imap/etc/imapd by default that has a
setting for the number of connections from a single IP address to
accept. It is MAXPERIP. Well, by default it was set to 4. It appears
that Outlook Express, at least, keeps the IMAP connection open. So
when you have a LAN of 50 users, it doesn't take very long for those 4
connections to fill up. It appears that if this limit is reached, the
server thinks it is an attack and stonewalls connections from that IP.
This just re-affirms my belief that Outlook and Outlook Express are
evil.
