lock z-push to a particular upstream version by fmbiete/Z-Push-contrib commit hash
the latest z-push introduces a new/second USE_FULLEMAIL_FOR_LOGIN parameter

see http://discourse.mailinabox.email/t/activesync-z-push-not-working/94/3
don't allow catch-all addresses in the admin because they take precedence over mail users and that's counter-intuitive

For now use the command-line tools/mail.py if you need it.

WIP: Switch from SMTP+STARTTLS on port 587 to SMTPS on port 465

A good argument for using 465 is made at
https://www.agwa.name/blog/post/starttls_considered_harmful.

FastMail make a good case at
https://www.fastmail.fm/help/technical/ssltlsstarttls.html.
(https://www.fastmail.fm/help/technical/servernamesandports.html states that
587 is available but they do seem to recommend 465).

Gmail uses 465 too.

This shouldn't stop opportunistic TLS being used for incoming mail because
STARTTLS remains available on port 25 - which is what would have been used
before too.
