<ADVERTISING> Have you considered Binc IMAP (http://www.bincimap.org/)? </ADVERTISING>
I'm pretty far along in the process (I hadn't heard of bincimap before). I haven't really had a problem with courier/vpopmail in the testing I've done with another domain (my synagogue), so I don't have strong reasons for switching now.
Care to send me mail directly with a testimonial?
