I haven't heard of that but most clients I have won't let go of pop3. When imap is used Outlook (and other mail clients) like to make quite a few connections to the server, it could be that some connections are getting refused. I've run into this and it's not an obvious problem. I usually increase MAXPERIP to 10, it's default is 4. The parameter is found in /etc/courier/imapd -- Fraser Campbell <[EMAIL PROTECTED]> http://www.wehave.net/ Georgetown, Ontario, Canada Debian GNU/Linux

This uses inetd for the pop and imap servers, and mbox mailboxes. It works fine, and seems to be the "best" set up for mbox mailboxes. On another machine I use postfix+courier-imap-ssl+courier-pop-ssl+procmail. Procmail is used with a global /etc/procmailrc to make postfix deliver into Maildir mailboxes. Courier uses a heap of it's own daemons for everything, which I didn't like, but it seems to work OK.

The big problem I found with Maildir is everything else seems to assume mbox (including the "you have mail" notification at the command line), and it's hard work to find and configure everything for it.

Courier-imap Outlook problem - RE: Imap && imap-ssl && pop3-ssl
We are using courier-imap in the configuration outlined on the marlow.dk website. One problem we keep having involves M$ Outlook clients. It seems that something breaks with the communication between the server and Outlook clients (or posssible corrupts the pst files created for each maildir). Has anyone else been faced with this problem? Since we are unable to convince our clients to move to Debian desktops with KMail or some other OSS alternative, some workaround for this issue would be greatly appreciated! Googling has not proven very helpful (only confirmed this as a problem).

Works like a charm. I know courier could handle everything with a single hand and half the overhead, maybe someday I'll migrate every mbox into maildir and set that up, but in the mean time, it does a pretty job.
