Witam,
mam server w ovh i na nim domene na IP FailOver.
Wysylajac emaila z tej domeny na maila w domenie Comcast.net dostaje zwrotke:
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:

Prosze o pomoc w rozwiązaniu problemu.
