I've recently built an entire mail system around FreeIPA and it works
great. There are two parts to be concerned with:
1. Authentication - With Postfix, this is handled by saslauthd which
can authenticate against Kerberos (using or not using sssd). I used
Cyrus-IMAP for the mailstore which also uses saslauthd. Doveccot has
it's own sasl built in which can authenticate against Kerberos or
LDAP, thus it should work with IPA.
2. Configuration - With Postfix, you can set all different areas (e.g.
virtual, aliases, etc.) to use LDAP lookup of configuration
information. You are typically searching for the email address (mail
attribute in IPA) and your search will generally return the userid
(uid attribute) of where the mail is to be stored. I don't believe
that Dovecot or Cyrus-IMAP have any way of maintaining any
configuration in LDAP so you generally have to setup mailboxes and
authorization information by hand using their tools.
