EXCHANGE/ Multiple Domain Names

[NTS]

There are two domain names for the company I work for.
Some people are setup with an e-mail address for each
domain, (e-mail address removed) and (e-mail address removed). The
user only checks the domain1.com mailbox, so I forward the
mail domain2.com to that mailbox.

For some reason when people write to the domain2.com they
will get a system admin failure reporting that the e-mail
address does not exist.

Can anyone help or is this just a big confusing mess?

Thanks,

Diana

Why not assign domain1 and domain2 addresses to the user in the same object?
You're hosting your own mail, not using POP anywhere, right?
