Backdrop: SBS Server 2011 running Exchange 2010. Outlook 2010.

We get the following message from one Fairpoint email address:
Connections originating from dynamically assigned IP addresses are not allowed. Please use your ISP's relay servers. ##

Where do I go from here?

This depends on your ISP.  Who are you using and I can most likely get you the information?

Well as far as I can see this could mean that your IP address (the one your internet connection uses, ww.whatsmyip.org will tell you) appears to be listed as dynamic. If you know you have a static IP address from your internet provider (which you should, otherwise incoming email to Exchange would be very problematic).

So it's very likely that the server you are sending to (recipient) is using a DNSBL that has your IP address listed as dynamic. Maybe ask the sysadmin of your recipient server to provide you wit the DNSBL (blacklist) and then have your ISP contact them to resolve the issue. Admittedly that's not the most easy resolution.

The second option is to simply use your ISPs outgoing mailserver. Usually something like "smtp.ispname.com", or "smtpout.ispname.com", or "smtpauth.ispname.com". You should have the details in your paperwork, or simply call your ISP to find out. You can then configure tis server as a "smarthost" within your Hub Transport settings in Exchange and that should then take care of the issue.

We are using a small local ISP and a quick call to them got a quick response - in fact they were very enthusiastic to solve the problem for us. Thanks!

You're very welcome. And I'm glad you got an ISP that is that attentive! The bigger the company the more impossible it is to resolve these things. Nice.
