I would very much appreciate it, if Falko could find the time, if the titled HowTo could be updated to Ubuntu 16.04 because a number of things (systemd!, Postfix) have been changed and updated since the last LTS. It would be very nice if the HowTo could include MariaDB, but that is not a requirement. I've used the howto for three LTS-versions of Ubunt server now, and without any problems. I have to add that in Ubuntu 16.04 that in 16.04 libpam/pam-mysql is seriously broken. Took me a while to find out, so an update is welcome for others as well. Thanks in advance! Martin
