Does the Droid have the option to send emails so that it looks like they came from a different address than the originating account?

Here is my dilemma:

I have two email address that I'd like to set up on the Droid. Both addresses are basically a string of random numbers and letters: X1Y2Z3@domain1.edu and A1B2C3@domain2.edu. Since both addresses are random and tough to remember, I have forwarding addresses that are linked to both: First.LastName@domain1.edu and First.LastName@domain2.edu.

What I would like to do is to be able to compose messages from these accounts or reply to messages received in these accounts so that it will show up as received from my forwarding address instead of the address which is the random string of letters and numbers.

Does anyone know if it is possible to accomplish this on the Droid?
