I've seen no indications of the bounces going to the list, only to
the sender (i.e. I posted 4 messages to freebsd-questions@ and got
back 4 bounces; I didn't get bounces that seemed related to anyone
else's posts).  However, it does look as if someone needs to teach
that mailserver about the Errors-To: header.

I let my uucp(!) upstream's Red Condor spam filter deal with that
sort of problem :)
