two domain problem

[Chipin]

Currently our set up is sbs2003 R2 with exchange set to use two domains, xyz.com and abc.com.

Exchange is set up with abc.com as the primary address and DNS pointers etc.

xyz.com domain is now causing more and more problems as email reverse DNS lookups are failing and outgoing mail is failing to reach the destination or ending up in the spam filter.

My initial idea was use my hosting company’s free POP3 services e.g., a catch all to receive mail and their SMTP for outgoing mail. However I can’t work out how to get exchange to send xyz.com mail out to my hosting companies SMTP port, while abc.com continues to go directly out over the net.

A second option would be to switch broadband providers, as one company offers a couple of IP addresses. This would allow two sets of DNS records to be set up but can exchange be set up to send and receive to the relevant IP addresses?

(outlook web is not currently and issue)

Any suggestions, pointers, opinions gratefully received!

Many thanks

Chipin

Chipin, this should not be a problem. You can set up an RDNS entry for each domain. They simply need to resolve to the appropriate MX record. Set each domain to use the same MX record.

Sorry Mark I don’t follow? I pretty new to all this.

The RDNS would only resolve to one domain or the other wouldn’t it? This is the current status of my setup.

You can setup both domains to use the same host name, so the RDNS for each will resolve to the same location.

To better explain you would need to post real domain names so I can use IPTOOLS to query your MX records to better explain.

I hope you find this post helpful.
