requested #550 denied by policy ##

Hello, one of our clients just changed their ISP and are now having trouble sending to certain domains. Most of them are government domains. We changed the reverse dns and the spf so we are certain that all is well there. We also verified that our client's IP is not blacklisted. When they send to certain domains, they get a bounceback saying "requested #550 denied by policy ##". We originally thought this was an issue with the receiving domain - however the originating server is that of our clients so I assume the problem is on our clients end. Any help would be appreciated. They are running an SBS 2008 server with Exchange 2007.

One additional comment I have is that when I try to email one of these domains from the clients server, I can see that the email is happy in the queue. It has a green status and isn't getting queued so it almost seems like it is leaving the clients server and then getting bounced back?

I would check with some of the public sources whether everything is setup as you expect.
Then check the FQDN on the Send Connector matches.

The remote side is rejecting the email at point of delivery, which forces your server to bounce the message. Alas the error isn't as helpful as it could be as to the cause.

Simon.
