[wplug] IMAP-secure and Postfix ?

I am currently running Postfix (it happens to be on FreeBSD, but in
application-space it shouldn't matter, right?) and my users would like me
to add IMAP.  My understanding is that imaps (port 993) is authenticated
IMAP and so the increased security risk is minimal.  I would then be
required to install OpenSSL.

The problem is, I don't understand where the MTA ends and the IMAP
behavior begins.  I've seen a couple quick-and-dirty howtos for IMAP and
Sendmail, but they aren't enough to explain the nuts and bolts.  I'm
currently working my way through the TLDP's "Postfix-Cyrus-Web-cyradmin"
howto (even though I don't want to use Cyrus), and in parallel I'm
re-reading the postfix and Courier-IMAP documentation, but this is a long
hard slog.  I'm reluctant to just dive in, since I and (at least one, soon
two) people sorta depend on this system for mail.

Can anyone recommend a good IMAP primer?  Particularly a postfix-related
one?
