* SMTP Submission (port 587) began offering the insecure SSLv3 protocol due to a misconfiguration in the previous version.
* Roundcube now allows persistent logins using Roundcube-Persistent-Login-Plugin.
* ownCloud is updated to version 8.0.3.
* SPF records for non-mail domains were tightened.
* The minimum greylisting delay has been reduced from 5 minutes to 3 minutes.
* Users and aliases weren't working if they were entered with any uppercase letters. Now only lowercase is allowed.
* After installing an SSL certificate from the control panel, the page wasn't being refreshed.
* Backups broke if the box's hostname was changed after installation.
* Dotfiles (i.e. .svn) stored in ownCloud Files were not accessible from ownCloud's mobile/desktop clients.
* Fix broken install on OVH VPS's.
Unfortunately our users/aliases database is case sensitive. (Perhaps I should have defined the columns with COLLATE NOCASE, see https://www.sqlite.org/datatype3.html.) Postfix always queries the tables in lowecase, so mail delivery would fail if a user or alias were defined with any capital letters. It would have also been possible to add multiple euqivalent addresses into the database with different case.
This commit rejects new mail users that have capital letters and forces new aliases to lowecase. I prefer to reject rather than casefold user accounts so that the login credentials the user gave are exactly what goes into the database.

This also includes fixes for a typo and some whitespace inconsistencies in
mailconfig.py. In fact the capitalisation change and those fixes are the
remnants of a patch I had been running that changed the default aliases - it
was through developing it that I found the issues.
(I wanted to bring the number of patches I apply before deploying to zero and
in the case of this one I've come to view the way MIAB already is as superior,
so I've undone the core of my patch and these tiny issues are all that remain).
A lot of legit mail servers try again between 200 and 285 seconds, then
3 hours later. Why? RFC is not strict about retry timer so postfix and
other MTA have their own intervals. To fix the problem of receiving
these e-mail really latter, I reduced the delay of postgrey to
180 seconds (default is 300 seconds).
* install the munin-node package
* don't install munin-plugins-extra (if the user wants it they can add it)
* expose the munin www directory via the management daemon so that it can handle authorization, rather than manintaining a separate password file
