I need some major help with configuring an Exchange 2007 Server. I have successfully setup Exchange 2003 servers in the past, but this is my first Exchange 2007. And I’m getting black listed left and right! So I know I must have missed a very important step along the way.

PROBLEM DESCRIPTION: I have a client who is running Exchange 2007 and their IP keeps showing up on various SPAM and BLACKLIST sites, which is making emailing a real pain.


DETAILED INFORMATION:

Server: Custom built Intel based server
OS: Microsoft Windows 2008 SBS Standard Server, 64 bit with Exchange 2007

1. Their domain is hosted with a company called Dream Host. This hosting company hosts their incoming emails as well as their website.
2. The SBS 2008 server pops the Dreamhost servers to download emails into Exchange once every 10 minutes.
3. Network Solutions is their top level registrar, but the domain simply points everything to Dreamhost.
4. Dreamhost has A records pointing to the incoming mail servers and their website.
5. I added an A record which points to “remote.cedarcreekinstitute.org” and this function works great to get me directly to the server running Exchange
6. I have setup a Reverse DNS entry with their ISP, which is “smtp.cedarcreekinstitute.org” and points back to 63.164.143.210.
7. This is a stand-alone server. Meaning there are no other servers on this network. I am NOT running Edge. I am using the Hub Transport ONLY. And this server sits directly behind a standard Linksys RV042 router. The RV042 is set to forward SSL port and 987 to the server and that is all. It is not forwarding port 25 as I have no need to have people sending email from the server unless they are physically in the building.
8. When I send a test email to my yahoo account, it always ends up in the SPAM folder. However, if I use the Dreamhost servers to send out from the same email address, it goes through just fine and does NOT get flagged as spam.

Here is a copy of the email headers coming from this exchange server (I have censored a couple of email addresses for confidentiality):

Finally, I am sending a few screen shots with my configuration screens, so you know how I’ve set it up.

Thank you very much for your help!
