uce not allowed on this network

Does any one know what this means?

"Sorry, UCE is not allowed on this
network. RT#341987."

A client of mine is receiving this message when he tries to correspond with a Realtor. He had previous (email)communications with this person without a problem.

My guess is that he replied to her message several times, always with the original messages in the body. I have seen this happen before when you reply to a message that has been sent back and forth a few times, always with the original content intact (in the body).

Does the message mean he has been flagged by a spammer from the corporate admin of the domain he is attempting to communicate with?

UCE = Unsolicited Commercial Email.

Rightly or wrongly, they think your e-mail is spam.

Thanks -- that is what I feared.
