Currently, I have domain1.com set as the default email address for the users
on this network. The company has registered domain2.com and want that to be
the new default email address they send out from but still want to receive
email from both domain1.com and domain2.com .. I was able to find threads
and setup email so that mail from both domains are received into the
corresponding email addresses. Now I just need the default email address
that they send out from to be domain2.com.
