last I checked, openldap, postfix and cyrus-imapd were free. What is the
cyrus-imapd doesn't use maildir but rather it's own methodology which is
similar to maildir but keeps all the mail in it's own partition instead
of users folders. It doesn't use system for quota management but has
quota management built in. It seems much more sane and permits 'virtual
users' which is/can be a virtue of ldap based accounts.
