Hmm, ok.

Pushing a recipient onto @Recipients will work *only* if stream_by_domain
actually does stream the message.  If the original message comes in
for only one domain, then adding a recipient to @Recipients will not work.

What you are trying to achieve is tricky.  At filter_begin time, you have
to check if the original message has already been streamed.  If it has,
then do nothing.  If it has not, then you should call add_recipient *and*
push the recipient onto @Recipients and call stream_by_domain.  Doing both
ensures that the recipient is added whether or not stream_by_domain actually
streams the message.

You can check the $WasResent global variable to determine whether or
not a message has been streamed.  (But it's a hack.)
