This reverts commit 703d356492.

Data loss will occur if backing up postgresql while it runs. A simple
fix is to stop it during the backup. I've moved the backup to early
morning to reduce possible downtime.

A better approach would be to use pg_dump.

The previous behaviour relied on managesieve copying over the
.dovecot.sieve file into the user's directory. I found this to be
particularly fragile. For instance, re-deploying roundcube without
dovecot could overwrite the .dovecot.sieve symlink and break
managesieve.

A better approach is to use the global sieve configuration that
roundcube provides and not mess with dovecot's files directly.

Properly behaving websites should 301 redirect the naked domain.

This prevents timeouts when trying to sync very large mailboxes. By
default, z-push attempts to get headers for all messages in a folder.

String-valued variables containing spaces can be substituted into an ansible
tasks file but they will not be interpreted correctly.

I had a # in my mail_db_password and spent the last 2 hours trying to figure out why I couldn't connect by IMAP. A # is only allowed if the connect string is wrapped in quotes.

Fixes issue #8. Adds new variable mail_header_privacy, on by default.
Installs postfix-pcre unconditionally, and then copies the pcre file
over and adds the header check to main.cf based on the variable value.
“this header replacement works great, but it logs that the replacement
has been done, which means that you are storing this information,
unless you are anonymizing your logs”

use the world-wide pool by default, but specify north-america in
user.yml. Also, documentation. This way Sovereign will still behave the
same, but the NTP servers can be changed when desired.

Otherwise only pop and imap (un-secured) are blocked.
Which we don't use.

This works on Debian/Ubuntu only.

There are similar packages for other distributions, but they still
need manual configuration. It seemed better to go for the common
denominator. unattended-upgrades is usually installed by default
anyway, so we are just reinforcing best practices.

added dovecot-pop3d
allowed in the firewall
monitored with monit
added relevant tests

Updated the default port to reflect MySQL to Postgres change (port 3306 to 5432)

* Added 'cipher' and 'auth' lines to the generated client configs

PostgreSQL works similarly with varchar and text columns. Rather than
limiting the amount of characters a column can hold simply use text
columns.

Because this sql is now PostgreSQL specific, there's no need to maintain
what was set in the mysql settings.
