 * fix mail_db_opendmarc_username/mail_db_opendmarc_password variable
   not found.
 * python-mysqldb package is required. Add it to opendmarc task.

For correct implementation of the fix for logjam attack (https://github.com/sovereign/sovereign/pull/372), state=latest is needed to grab sufficient version of Dovecot. If not then 37aa7e2cb5 doesn't work.

See https://wiki.mozilla.org/Security/Server_Side_TLS for details.
Removes RC4 cipher. Fixes issue #341.
Also explicitly disabled SSLCompression and enables OCSP stapling.

We should put all these settings in
/etc/apache2/mods-enabled/ssl.conf
to avoid duplication...

(on Debian Jessie, Ubuntu Trusty or older distributions such as
Debian Wheezy and Ubuntu Precise).

Resolves #363.

Addresses #362.

ahbl is no longer being maintained and has been configured to return a
positive value for every host.  This means I get a cron warning every
day reporting that my mailserver is in ircbl.ahbl.org and
dnsbl.ahbl.org.

lukecyca/check-rbl#1 has removed ahbl from the blacklists that it
checks.  This just pulls in that change.

Unfortunately, ansible's get_url won't update files which have been
downloaded already unless you set force=yes, which will cause ansible to
pull down the file from github on every single run, which isn't really
acceptable.  I have filed ansible/ansible-modules-core#625 to ask that
get_url redownload if and only if the sha256sum differs.  In the
meantime, you have to manually delete /opt/check-rbl.pl before rerunning
ansible to pull in the update.  However, at least this will work fine
for new installs.

Related to #338 (though I don't know if it truly fixes it).

to mitigate POODLE vulnerability

Postfix: Disable SSLv2 and SSLv3 for 'mandatory SSL' mode connections to completely mitigate the POODLE issue.

Disable SSLv3 in Dovecot imap server to avoid POODLE vulnerability

Resolves #114

* Postfix: Trusty comes with postgresql 9.3, not 9.1
* owncloud 6.0.1 is part of the distribution, doesn't require opensuse repository
* owncloud requires libapache2-mod-php5
* uses prosody repository that matches the ansible_distribution_release (trusty, wheezy, etc)

Fixes #232

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.

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