Mad props to those two links above. Thanks the documentation of these two guys, most of this configuration was possible and is indeed shamelessly copied from their links above.

Requirements

This was only tested on CentOS-7 and you should probably already have the epel-release package installed. Also, this setup assumes you are running your mail-server behind a HAProxy (eg. see dovecot / postfix config-templates). Do check the dovecot LDAP setup and give a proper URL to your (eg. freeIPA) LDAP server. For openDKIM, you need to setup keys in DNS for your domain to make things work. Also, please double-check all config files and setup proper values for your environment, if things should not work out of the box.

TODO

Some values (user-id, path for mail-user) are still hard-coded. This should probably be configurable via attributes.
