smart email from dummy domains?

[michaellunsford]

We have one domain that has all of the email setup properly. Now the client wants to add a bunch of "dummy" domains to the same list.

for example, we'll say "example.com" has all the email setup. He also owns example.net and example.org and wants email written to [email protected] to go to [email protected].

This is probalby a solution that's in here somewhere, but I just don't know what the right terms to search for are.

Any help would be greatly appreciated.
