An interesting question.  Here are my statistics for the last few days:

1 Recipient:  1666 e-mails
2 Recipients:   34 e-mails
3 Recipients:    6 e-mails
4 Recipients:    3 e-mails
5 Recipients:   16 e-mails
6 Recipients:    3 e-mails

The blip for 5 recipients was from a spammer trying the same five
recipients.

So you can take from this that the cost of streaming by recipient
is usually low.  You can also play tricks to convert what would normally
be a bounce into a DISCARD if you know that mail has been streamed.
This eliminates the need for your machine to generate bounce messages.
You have to do this very carefully, though, and only convert a bounce
to a discard if you're pretty sure the original message is spam.
