RBL restriction: Blacklisted by Internal Reputation Service

New Poster

RBL restriction: Blacklisted by Internal Reputation Service

When I send an email from my internal mail server to tds.net, q.com, centurylink.net, embarqmail.com or elknet.net, I am recieving a bounce back of "550 5.7.1 [C15] RBL restriction: Blacklisted by Internal Reputation Service - 50.194.197.41."

 

I appear to have the same issue as in this post: http://forums.xfinity.com/t5/E-Mail-and-Xfinity-Connect-Help/RBL-restriction-Blacklisted-by-Internal...

 

Comcast, Can you look into this?
