You can minimize this by checking in filter_begin to see whether all 
recipients have the same policy.  (Or at least see if they all use the 
default policy.)  Then only call stream_by_recipient if their policies 
differ.

Also, if you have any universal rejection policies that you can apply in 
filter_begin, do those before the call to stream_by_recipient.

That way you can still issue SMTP rejections in most cases, and bounces 
are limited to specific circumstances.
