Exchange Server Configuration

We have a similar configuration to what you want to set up. In our case, we established 1 way trust from the domain where the exchange box lives, to the domains where the users are located. The user domains are the trusted domains. Then, you'll beable to create mailboxes on your exchange box, and tie the mailboxes to the user NT accounts in the various user domains. We haven't had problems, and the trusts have been stable, even over our WAN Links to remote sites with their own domains.

You need to
1,. Make internet DNS's max record point to your exchange server.
2.- Add the domain name list into the domain allows to recieive emial from in exchange configuration, using a ; between each domain.
Up to now if you have dom1.com anddom2.com and a user named u1, any mail recieved by the server to u1@dom1.com or u1@dom2.com will be delivered to u1.
3.- Next you need to join another exchange server (e.g.:with dom2.com configured) to the same site by making a two way trust relationship or by setting up the x400 connector (not fully recomended)
4.- Exchange MTA's will automatically knows where the domain resides and will start following emails to that domain.
5.- Be carefull: If you have two users named U1 in both domains, the e-mail will be forwarded to the domain close to the exchange internet agent.

Hope it helps!!

Is this still a problem?
