I have been wading through the admin manual and the answer to this questions is not clear... so please pardon my newbee lameness...
Created a mail server whose hostname is: mail.foo.com
Using the web client, all users are created as email@example.com.
That is not what we want. What we want is the users created as firstname.lastname@example.org
Do we have to create a different domain to do this? What is the procedure here?
I am totally lost. Any / all help appreciated.
