SBS 2003 and Exchange problem - mail is bouncing back when sent through ISP.
there's an SBS 2003 server at location 2 of a multi location / pretty autonomous business (location 2 is pretty independent of location 1). Location 1 is home office and has a domain / email hosted by outside ISP (domain1.com). location 2 uses the same company and has domain2.com. their addresses are bob@domain2.com, etc.
but they check email at webmail.domain1.com. mail to bob@domain1.com and bob@domain2.com show up in their outlook mailbox of bob@domain2.com
we set up pop connector to get email from ISP and is working good. sending mail out through ISP gets:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<domain1.com #5.5.0 smtp;553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)>
do we need to rerun the internet and email wizard and send using domain1.com!?
thanks!

Is this a repeat question? I coulda swore I saw a comment by Sembee on this exact question earlier suggesting you contact your ISP.

"that domain isn't in my list of allowed rcpthosts" sounds like another way of saying that they will not relay for you. Are you sure you are using the right mail server for your ISP? If you have a static IP, check your IP on the spam database at http://www.DNSStuff.com, if it doesn't have any rejects, start sending direct instead of sending via your ISP.
You may also run the full DNS Report (http://www.DNSReport.com) to see if there are any other issues with that setup.
Unless you are using the wrong outbound server as a smart host, it does sound like the problem lies with the ISP.

Sorry for the cross post. I was eager for the answer and wasn't sure where to get the answer the quickest. I am making it a 20 popint question so I can close this out. sorry!
FYI - the answer for us was the be sure our ISP installed a PTR record.
