2 Exchange Servers not sending emails between

[gbecker]

I currently have two exchange servers. 1 for domain xyz.com and 1 for domain abc.com. For the most part each email server has different users. The problem I am having is for a user that is on the domain xyz.com and has an additional smtp record for abc.com.

I have 10 users on the xyz.com domain that have an additional smtp records for the domain abc.com. I set up a receipt policie for abc.com. And on the Abc.com box I modified the messages tab to send all undeliverable message to the axy.com server. If a person externaly send a message to the abc.com domain the message goes to the abc exchange server and then if not there gets forwarded to the xyz.com exchange server. This way the other 10 people get the messages.

Ever since I added the abc.com smtp to the xzy.com user I get the following problem. When any user on the xyz.com exchange server tries to email anyone on the abc.com domain they get a undelieverable. Any help?

How do I make it so the xyz.com domain will look at the abc.com domain for email address? If I modify the undelieverable messages then I get stuck in a loop.

Thanks
Glen

Are those two servers in the same Exchange org?

How are the recipient policies defined?

XYZ Highest This exhcnage is responsible of del...
abc 1 This exhcnage is responsible of del...


User email address

smtp user@xyz.com Primary
smtp user@abc.com

Ah - you might want to configure that server to send any unresolved email to the first server.

Since you have the abc.com domain as part of the recipient policy for that server, Exchange thinks it's authoratative for that domain. Since it doesn't see an address locally, it doesn't think there is a match, and bounces the message.

On the abc.com Domain I have exchange setup so it forwards all undeliverable messages to xyz.com.

You are now telling me to set xyz.com up to forward all undeliverable messages to abc.com.

Won't that cause a loop? If we get a bogus spam message won't it bounce back and forth?

Please advise and thanks for your help.

A mail message should be configured for one of the domains housed by your servers. It shouldn't bounce around.

Ideally, both Exchange servers would be part of the same org, so that the same recipient policies could apply to both. Things would be much better that way.

Is there a potential for a mail loop? Yes. But I think that's going to be your best solution for having two separate servers handling email for two domains when they are not part of the same org.

Can you please explain the above statement?

What I meant was that the message is bound for an address on one of the servers. It should get delivered by making no more than 1 hop.

Again, this isn't an ideal solution. Both email servers should be in the same org.

Wouldnt it have been a lot easier to have all the users on the other domains fwd the mail to there primary domain ?

i.e if a mail comes to a@abc.com fwd it to a@xyz.com
outlook rules could be used even.
