I'm off-kilter, but that's just me.

If someone that is on a DNS RBL sends us an e-mail and that e-mail gets
rejected, the sender almost immediately gets a report stating why the message
wasn't delivered. I've had a dozen or so clients call us already wondering why
they are getting these messages. I add them to our internal whitelist and tell
them how they can *possibly* remove their domain from the BL. I'll actually sit
here with them and check the many blocking/black lists to see if they're on one
of the lists we subscribe to. This site rocks:

Maybe it is the perception that it could be *their* fault that the e-mail didn't
get delivered. If they think it is *our* fault, they don't care. They seem to
pay more attention to a 3rd party message than they would a message from the
recipient's domain.
