IMAP-before-SMTP?

[Adam McKenna]

Is there an IMAP server around that plays with qmail's tcp.smtp file (the way
vpopmail does) for IMAP-before-SMTP?  I suggested POP-before-SMTP to a
client, but they are strictly IMAP, and they need IMAP-over-SSL.  I then
suggested SMTP AUTH using CRAM-MD5, but most of them are using Netscape Mail
which doesn't support this.
