IMHO I think that between the two of us we are playing with the top 2 mail servers in the world! But no one is really absolutely certain which is first because it all depends on what's your "itch".
Next regarding IMAP(S) for Maildir/ One of the newest I recommend is Binc, or bincimap.. It is designed for Maildir/ only, 10,000s of lines of C code less than all the others, very fast, and just came out for production. It is a natural for qmail, as it uses the same checkpassword as qmail does. It is very easy to set up, and run with it using SSL. I use it exclusively for the servers I build. In beta, it was tested by a firm with over a 50,000 user base with no problems..
I have heard of Binc, and dovecot as two potential solutions but haven't been able to find much in terms of endorsements anywhere. I think I'll give Binc a try. BTW - This leads me to another very generic question: mbox format -- email is seperated by a string like /^From / at the top of each email. In this string is the Envelope Header (MAIL FROM) in my messages. Two question: Postfix puts the Envelope Header into /^Return-Path: / -- True/False? Does maildir provide a similar format or at least embed the Envelope Header into the email if postfix doesn't?
