It was simple to resolve. I just had to zap the services to a stopped state and start and things came back up as normal.
I personally use courier-imap for pop3, pop3-ssl, imap and imap-ssl and it works very well. Another poster pointed out the virtual mail guide on go.org. I recommend having a look at that. However, there is no reason to stop using qmail as an mta if you already have it configured to do so. Unless of course it matters to you that qmail isn't open source software http://www.qmail.org/not-open-source.html then you may want to look into using an mta like postfix. Anyhow, I personally think courier-imap works quite well. To answer your question, yes you will need courier-imap if you want to retrieve mail from external mail clients using pop3 or imap. > Anyway, I entered a bug (http://bugs.gentoo.org/show_bug.cgi?id=80879) and > have been > discussing what I may have done wrong and how to avoid any problems.

If you overload your servers, which schools tend to do and everything runs like crap. HTH, Wendall
