      If your mail had a valid sender domain, it would be their
      problem. Maybe a temporary DNS error, give it another try.
      (but they shouldn't 550 reject on a temporary
      error). Check your dns at dnsreport.com.

            So you need to set and A record for your espphotography.com domain.

              This is not true. There is an MX record for espphotography.com, so an A
              record is not required.

              $ host espphotography.com
              espphotography.com mail is handled by 10 ns1.peskin.org.
              espphotography.com mail is handled by 5 phirephoto.dyndns.org.


              Maybe this is related to the use of dyndns.org, which is really a bad
              idea for an MX.

                  If this address is not modified by relay, then the problem is probably
                  at comcast side. seems like an access control check (would they block
                  domains with an MX at dyndns?)
