If you just need to give end users access to email and email directory

DMZ system, allow port 143 (IMAP) and port 389 (LDAP) to an exchange

I would suggest imaps(993) and ldaps(636). If your webmail client
doesn't support that, zebeedee or stunnel could help in creating the SSL
connections.
No use running plain text all over the place when SSL certificates are
free.

What is the point of running SSL connections from the web server front-end
to the mail server back-end?

If the web server gets owned, I would argue that this ADDS exposure, 
not the other way around.
