	Note that MTAs have to look at the number of "Received:" headers 
that are on messages, and if the count is higher than a certain 
threshold, they will assume that there is a mail loop and bounce the 
message.  Many MTAs place this threshold at around seventeen hops.

	It would seem to me that your ISP is screwing you around by the 
way they are passing around e-mail internally to their network.  Get 
them to clean up their internal routing of e-mail, and this problem 
should go away.
