| Hi,
My scenario is as follows :
- On DMZ i have IIS SMTP server
- On LAN i have Exchange servers and Unix servers
My requirement:
I have a user called user1@test.com on Unix box.
Rest of my users are on Exchange.
Now, I want any emails destined to user1@test.com getting directly relayed
to Unix box by the SMTP smart host on DMZ.
Can this be done by scripting..because i guess there is no relay forwarding
on SMTP based on username.
Any help appreciated.
thanks,

Not really. The domain has a MX record, which is where the mail for
that domain gets sent. You have two mail servers with the same
domain, so it's pretty near impossible to separate these until it's
been processed by a mail server. While I'd question the wisdom of
having a single user on th Unix mail system, your best solution is
likely a forward from a mailbox on Exchnage for that user.
