Yes.  CanIt-PRO does this.

Basically, you build up "equivalence-classes" of users who all want
the same kind of processing.  If the message recipients are all in the
same equivalence-class, you just process it.  Otherwise, you re-mail out
copies (one per equivalence-class) and discard the original.

That's the concept.  The code is proprietary. :-)

But a hint:  Take a look at stream_by_domain.  Very minor modifications
to that function will do what you need.
