Charter.net SMTP IP blocking

Cdns01.comcast.net can't find 76.127.79.67: non-existent domain. 

That is the IP that Charter.net is blocking on port 587. Please fix this IP range (new service address in Modesto CA)

@user_ffca83 Charter requires a PTR record for that service, which seems to be lacking on that IP (it should be there). I'll see if we can get someone to put one in place.  May take a day or two.

@XfinityRuben​ Thanks, I believe that Alex has already made the request, and I am now able to send emails from my Charter account.

I appreciate your attention to this, both of you! :)
