My problem with COMCAST to EMBARQ turned out to be that my IP address is for some reason blacklisted. EMBARQ finally addressed the problem of no error message so I at least knew I was not getting through. The solution for me was to have all of my Embarqmail recipients add my email addresses to the Embarqmail address book at the Embarqmail webmail site.

FYI: No matter from where you send a message (Hotmail, Gmail, Yahoo mail, the Comcast webmail, etc), your real IP address is inserted. If it is blacklisted, you are up the creek.

I am also having problems sending to some of my Verizon recipients from COMCAST but only some of them. I get no error message and they get no note. But they can send to me. Frustrating!!
