The man page isn't too extensive on this. At a first glance it seems that calling stream_by_recipient in filter_begin does not trigger the code in filter_end, for instance. So if  stream_by_recipient is true then only filter() is run?

How do you do that?
Do you use resend_message()? (but that resends immediately the ORIGINAL message)
