== INVESTIGATION 2: SETTING UP MTA FOR RECEIVING EMAIL A CENTRALIZED MESSAGE STORE ==

=== Specifying Which Domains are Used Setup Your MTA to Send Mail MessagesUse Correct Domain===

As of last labIn Lab 4a, both of your email servers are were sending mail messages addressed from users of the actual machines themselves. This would be confusing for the receiver who might get emails from the same user @vm1, vm2, and vm3. Which would they respond to? To avoid thisproblem from occurring, we can make all servers make the sent mail appear to come from a common central location (usually the '''domain'''), and make incoming email sent to that address to be accessible from machines inside within our network.
