Not receiving emails from a domain

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.
