Reverse lookup seems to be working for these ips. One possility is
that the receiving mail server is trying to match a forward A record
with the reverse PTR for 69.56.237.82. if mail is in fact coming
from 69.56.237.82, some receiving smtp servers will deny a connection
from it because there is not forward A record for spameater.com that
points to 69.56.237.82.

Just a guess
