mail rejected due to execssive spam
We are getting reports from someone trying to email us that any messages they send us are bouncing back to them. We are trying to determine if this is a restriction on their outgoing SMTP server, or if it's a problem with our incoming SMTP server. Here is the message they receive when they try to send us mail:

I received an email from our ISP who indicated there is a problem with the sender's mail system, which indicated the name spamkiller.pjm.local was not being resolved to a valid internet IP address (obvious), and that is probably the cause of the problem. I tried sending a message to an invalid email address from our ISP's SMTP server and received a similarly formed bounceback, which led me to identify the cause being Godaddy rejecting the mail because something was invalid. I'll write back here once I confirm this, at which time I will probably accept PsiCop's response, with assistance from cagri (split points).

After a lot of back and forth with this person, we finally convinced them the problem was on their side. They had their IT person make some changes and viola, we are now receiving email from them again. I was unable to find out exactly what they changed, but I am pretty sure it had to do with changing that FQDN to a valid Internet domain name.
