Hmmm. Is Marc P forwarding to arbitary domains (e.g yahoo) ? As I
understand it, he simply delivers to his own customer servers (not yahoo).
If one of Marc's customers were silly enough to blacklist Marc, only that
customer would be affected.
So it sounds like the sender callouts must be responsible any for listings
in public blacklists.
