And the originating IP reverse resolves to: ydyn.com
which also doesn't resolve.
For many / most anti-spam solutions three
configuration issues are important:
a. The HELO name reported by your server should be valid AND
resolve to the IP Address mail is sent from
b. Reverse lookup of the IP address needs to match the
forward name
These rules keep getting tightened. I finally had to stop using the
GnatBox DNS because I couldn't figure out how to get it to process
my ISPs CName delegation for the PTR record. AOL started refusing to
accept my email.
Could be that GTA is testing a new version of their anti spam filtering.
So it stopped working for your mail.
If you check your from IP with the black list search services, I'm sure
you'll find your mail will be blocked. I use www.dnsstuff.com, but it
seems like they are often overloaded and the server returns nada.
