I have created a user account called 'whitworth' but I want his email address to be 'worm'. I had to do this, because someone else has already picked worm to be their username, but it is not one of my accounts, and not in one of my domains. I can login through the webmail interface with the username 'worm' but all mail sent from it looks like it's coming from 'whitworth@'. When I click on mailbox settings it tells me:
**** Whitworth's Mailbox Manager (worm@*****.com)

Is there I setting I missed?
