Ken,
Did you configure reverse DNS internally or through your ISP?

Looks like a reverse DNS issue - check out the #550 Access denied - I think when last I was looking into this, that's what I was finding. Once I got reverse DNS configured the error went away.

So, if you have reverse DNS configured, make sure your private IP is allowed to "send" from your Exchange server. I believe you just need to add that IP to your "Internal Client Relay" list if using Exchange 07.

Hope this helps!

Guys,
I am trying to figure out if the message below (and other like it) is a problem on our end or the receiver's. Can someone help me out? The only think I can think that concerns me is that our private IP address is listed below, instead of our public...is that typical? It happens during a BCC mass email. We know the address is good.

Any help would be appreciated.

Dan
