Majic Ansible Roles currently does not provide ability to customize the maximum size of incoming mails in the mail_server and mail_forwarder roles, and relies on Postfix's default of 10MB (10240000 bytes)

This has resulted in ugly hacks being deployed for Majic Infrastructure to allow sending of larger mails during the COVID-19 pandemic.

In addition, it feels like this kind of option would be very useful for the role (since mail size is something that may need to be changed on relatively regular basis as time progresses).

The following should be done:

• Update the mail_server and mail_forwarder roles.
  • Add parameter mail_message_size_limit
  • Make the mail_message_size_limit default to 10240000 bytes.
• Update role reference documentation.
• Update release notes.
