Ok, this user is using my courier as a relay (authenticated smtp), however
64.80.255.252 is NOT my server's IP. My server's IP (the relay being used)
is 38.118.152.246.  I'm guessing that perhaps that is the IP of his email
client? But if so, it doesn't make sense because shouldn't the IP be the one
of the email server that is relaying the message?

So I'm confused. The person says he has already sent an email to
all...@jo..., but I guess that hasn't helped.

My main domain is indeed americasnet.com... however that is not the domain
that the user is providing when utilizing the relay. Which domain would I
need to add to spf.pobox.com ?

Yeah... however the person claims he has already done that.

I guess a better question is, what exactly is the error? Is it the
destination server (joimail.com) rejecting the message because of some
misconfiguration on my server?

Thanks again
