I've been trying to get an email confirmation from nopixel.net for an account I made there for a few months now and haven't been able to receive any, hoping to get them unblocked if they somehow are.
@kdurdeen3 The domain nopixel.net is failing to send to Comcast due to a 554 error(reference: http://postmaster.comcast.net/smtp-error-codes.php#554)
554 - [PTR lookup failure] | Comcast requires all sending mail server IP addresses have a valid PTR record set up. This error results when the lookup failed. NXDOMAIN response. One of the authoritative servers for the relevant section of the in-addr.arpa DNS tree is saying that there is no PTR record for the given IP address. |
the domain nopixel.net will need to resolve this in order to be able to send to the comcast.net domain.
