Password is not necessary when using a trusted
connection (localhost).  Tested by moving mail in and out of Junk
folder while monitoring `/var/log/rspamd/rspamd.log`.

Rmilter [is no longer
needed](https://rspamd.com/doc/quickstart.html#rmilter-setup) as of
Rspamd 1.6.

This patch finalizes the switch to port 587 for email submission that
was started with commit 166c57.

Currently client email is submitted via ssmtp (port 465).  This has been
deprecated for years.  The correct way to submit email is via
submission (port 587).

This patch adds port 587 as a second and the default way of submitting
email for delivery.  Port 465 remains open for backwards compatibility
with existing clients.

An earlier commit started transitioning opendmarc to use postgres, but
this was incomplete.  This patch reverts that change and uses mysql for
the reporting database.

Other changes:

* Do not maintain a copy of the database import schema.  A copy is
  included in the distribution in /usr/share/doc, so that is used
  instead.
* The configuration file is replaced with the distribution's sample
  configuration.  A second patch will restore the actual configuration.
  This will make the changes easier to see if the default configuraton
  file changes in future versions of opendmarc.

Take changes to the tomcat6 default configuration and apply to tomcat7
configuration.  This was done by review of the diff between sovereign's
tomcat6 configuration and the default tomcat7 configuration.

The package solr installs and uses tomcat7.  Installing tomcat8 appears
to be a mistake for Debian Jessie.

Disable SSLv3 in Dovecot imap server to avoid POODLE vulnerability

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.

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”

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

This allows the `recipient_delimiter` setting in etc_postfix_main.cf.j2
to function as intended.

Fixes: #121
