Yes, but after they time out a bounce will be generated. If the bounce ends up going to the same place, you"re back to square one.

You should examine your bounce process. Whatever you"re doing, your bounces should have a null envelope sender, so that a double-bounce gets flushed.

hmm.

Would this be caused by having post@me.com in the dsnfrom ?? Should I leave this at <@> ? I was getting a lot of rejects from braindead servers that refuse to accept mail from <@>.

dsnfrom only sets the mail header, which is irrelevant. The envelope sender is always null for bounces.

Your mail filter must detect double-bounces going to the postmaster mailbox, and disable all filtering for them.
