Changing email domain in Exchange

tmckinney01 asked
Having trouble gettng my head around this one.  I have a customer running SBS 2008.  Let's say their external domain name is "xyz.com"  The external DNS records for that domain point to their server, so all mail to that domain is sent there.  They just purchased a new domain name, say "abc.com".  They now want to use that for their email.  I am fine with pointing the new doamin to the server and changing the domain in SBS, but they also want to continue receiving mail from the old domain for a while; how can I set it up for mail from that one to also be delivered?

You would need to change the MX records in the domain zone file. Run nslookup and 'set type=mx' to lookup the domain for the current settings i.e.


> set type=mx
> google.com

Non-authoritative answer:
google.com      MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
google.com      MX preference = 10, mail exchanger = aspmx.l.google.com
google.com      MX preference = 40, mail exchanger = alt3.aspmx.l.google.com
google.com      MX preference = 50, mail exchanger = alt4.aspmx.l.google.com
google.com      MX preference = 30, mail exchanger = alt2.aspmx.l.google.com

alt1.aspmx.l.google.com internet address =

Once you have completed above update the recipient policies in Exchange for both domains
