Author Exchange relay for Exchange
NewGuy

2005-05-24, 6:03 pm

I am trying to get one exchange server to send email to another. Server [a]
would receive email that is sent to it from outside the network. I have
created another domain with exchange server [b] this domain is in its own
forest etc. I would like to some how allow server [a] to receive the email
as it normally does, but relay email that sent to domain [b].

Each time I try to do this I get an error message stating that server [a]
can relay.



HELP Please

Have you tried posting in an exchange newsgroup? None of these that you
have crossposted to are exchange newsgroups.

The Exchange Servers must be in the same "Exchange Site",...that won't
happen if they are in different Forests. You will have to operate each
Exchange Server independently of each other.

Post in the proper group,...preferably only one group.

Once the email gets into Exchange it is not possible because you have
two forests. It may be possible to do something with IIS SMTP, but it
may be more useful to put another server in front of both of them with
forwarding rules. Qmail MTA, for example, has a very simple system
/var/qmail/control/smtproutes:

domain1.com: server1.domain.com
domain2.com: server2.domain.com

There are plenty of other systems that will do this for you. This
also adds the advantage that the Exchange server is not directly on
the Internet, and that you can put antivirus/spam software on the
gateway mail server.

Thanks.
Andrew.

Eh?
Why couldn't Exchange route mail destined for that second domain? That
would be a normal everyday use of Exchange IMHO.

Can you add some details as to why Exchange wouldn't accept for both domains
and act as a message router for that second forest?

Normal everyday for Exchange when *properly installed*. Properly
installed means they are in the same Exchange Site,...which mean they are in
the same Forest.

No, that would not be required IMO and experience. I could use separate
forest topology and still route appropriately.

Maybe something else I'm not aware of was preventing the use and making you
want to go use some other MTA? QMAIL was what I think you specified.

To be honest, I can do that with either Exchange or some other MTA that
understands how to route based on domain.

Was there something else?
