Doug,
This is an example of 'deep-scanning' and not connection rejection based
on simple blacklisting. The server is taking in the message and then
analyzing the content of the message along with IP and domain based
tests, and is then rejecting it. This explains why some messages work
and others don't.
secureserver.net = GoDaddy = you get what you pay for. This could be
anything from bayesian filtering to pattern filtering to URIBL
filtering, etc.. No way to tell based on what you are getting as an
error. In GoDaddy's defense, they clearly have a lot of customers that
try to spam, and they appear to have tightened the screws very tight.
It's tough to serve millions of domains and manage abuse. Your problem
will go away if you can find another server to relay off of. It also
appears that you are handling E-mail for Internet cafes which are
notorious for having their connections used by spammers and users with
infected computers, and this may help explain your issues.
