Examples: 1. SMTP and POP server twistd mail --maildirdbmdomain=example.com=/tmp/example.com --user=joe=password Starts an SMTP server that only accepts emails to joe@example.com and saves them to /tmp/example.com. Also starts a POP mail server which will allow a client to log in using username: joe@example.com and password: password and collect any email that has been saved in /tmp/example.com. 2. SMTP relay twistd mail --relay=/tmp/mail_queue Starts an SMTP server that accepts emails to any email address and relays them to an appropriate remote SMTP server. Queued emails will be temporarily stored in /tmp/mail_queue. c � � t j j | � t j � | _ d| _ | j D ] }g | |< � y)z: Parse options and create a mail service.
