Tighter integration with website

Great module - finally got it working!

This seems to be a natural partner to cPanel, which allows me to create an email address such as drupalUserName@mydomain.com.

When I compose and send an email using pontomail the receiver sees the senders email address as being the one associated with the Drupal user. In other words, it sets the senders email address based upon the drupal email address instead of setting it as the user name (email address) stored in pontomail_server. Is there a way that I can force pontomail to set the senders email address as the one stored in pontomail_server as the username? Clearly I need to retain the users original email address for general system communications.
