The nth recipient has to wait for n queue intervals to get the message.
If n is 10 and the sender's queue interval is 30 minutes, that can get
pretty annoying.

In theory.  Another problem in practice is that a lot of
widely-used-but-marginal SMTP clients don't react well at all to a
tempfail in response to RCPT, and end up bouncing the message.
