Hi - as of yesterday, I cannot send from emClient to anyone with a comcast.net email address. I get the following message:
Your message cannot be delivered to the following recipients:
Reason: Rejection greeting returned by server.
Diagnostic code: smtp;554 resimta-ch2-20v.sys.comcast.net comcast 126.96.36.199 Comcast requires that all mail servers must have a PTR record with a valid Reverse DNS entry. Currently your mail server does not fill that requirement. For more information, refer to: http://po
Remote system: dns;mx2.comcast.net (TCP|188.8.131.52|59768|184.108.40.206|25)
I can send to comcast via my iPhone without any problem. Does anyone know what in the world changed?
