* 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)

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.

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

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

Remove all configuration for MySQL and configure PostgreSQL as the main
database.

All *_mysql_* options have been changed to *_db_* options.

Postgres requires the database user to have a password in order to
connect via localhost. The db_admin_password option is used to set the
password of the admin user (usually postgres).

Use the changed `mail_virtual_users` structure to ensure directories and
sieve rules are created for each defined account.

mail_virtual_xx list were not use correctly in tasks.

We got error 'unicode object' has no attribute 'name' because:
with_items:
 - "{{ mail_virtual_xx }}
is understood has a list of strings containing information extracted from {{ mail_virtual_xx }} variable

 Now we use:
   with_items: virtual_domain_xx}}"

These are the changes necessary to enable Roundcube's manage sieve plugin to mange server-side sieve filters.

Move the settings of the virtual mail directories into a separate
ansible task.

Without the owner being set to vmail and dovecot, when a virtual user
tries to access their mail account, dovecot throws an error that it does
not have permission to create the mail folder for the user.

With the owner and permissions being set the user's mail directory is
created and they can successfully sign in.
