I just updated my Ubuntu mail server recipe for Ubuntu 16.04 (<a href="https:&#x2F;&#x2F;www.exratione.com&#x2F;2016&#x2F;05&#x2F;a-mailserver-on-ubuntu-16-04-postfix-dovecot-mysql&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.exratione.com&#x2F;2016&#x2F;05&#x2F;a-mailserver-on-ubuntu-16-...</a>). It only took a day of work to find all the holes and fall into them.<p>Everything core Ubuntu and core mailserver worked fairly well. The standard issue Apache&#x2F;PHP 7 seems to have some odd kinks around the edges, though - at one point the only thing that worked to make it recognize a newly installed PHP module package was to restart the whole server. I have to wonder if this was something relating to systemd, but I&#x27;m not familiar enough yet to tell.<p>Subsidiary packages had a number of issues, but this is probably just standard PHP ecosystem raggedness at the edges for a new distribution. The Roundcube version installed via package is just outright broken due to bad symlinks, for example.<p>On the whole I was pleasantly surprised as to how much of a nonissue the transition to systemd was.
