I have Exchange 2003 SP2 running on a 2003 DC. It has worked flawlessly for close to 5 years using a dynamic IP. I bought a new box because about once a week I'm getting blue screens related to hardware. On the new box i'm testing MSE 2007 SP1 on a 2008 DC using the same dynamic IP. The router is still forwarding ports to the 2003 box because I can't take it offline until the 2007 box works. To test I am using OWA with the administrators account. From a client I log into OWA and most domains I email to are returning NDR's or delayed delivery which eventually fails. Below are some examples:

mx.bigfoot.com #554 Access denied from 72.129.57.xx. See http://www.us.sorbs.net for more information ##

fujitsu2.fujitsu.com #550 5.7.1 <william.kendig@us.fujitsu.com>... Mail from 72.129.57.xx blocked using Trend Micro RBL+.

I thought it may have something to do with the spam filter script that comes with 2007 so I uninstalled that but the problem persists. I email to these same addresses from the 2003 box, using same external dynamic IP without issue. Please advise.

After doing more research online I think I 've left out pertinent info. The new 2008 server box is a different domain name than the 2003 box. We have multiple domain names and the one on the 2003 box really isn't significant any longer although it's configured to accept mail for many other domains. Could a certificate be the issue? I remember having to create one for the old server but the reasoning/problem escapes me as it was quite some time ago. Thanks for any assistance...
