Secure IMAP server

[Rahsheen Porter]

I'm extremely happy with qmail and the other software available from
DJB, but I've yet to hear anything about an IMAP server that takes
security into consideration. I'm running Courier-IMAP right now, but I
haven't actually opened the port to the world yet because I'm not
confident in it's security (since I can't seem to find any docs on it
that mention the word). 

Any recommendations on this subject?
