The IP that's checked in the DSBL is the one of the machine opening the
connection to the MTA running at murphy/master. You don't actually
scan the email headers. You are right that the bandwidth is decreased
only if the mail is rejected instead of being just tagged, of course.

Bandwidth is much more expensive than CPU time. The bandwidth required
by the DNS lookups can also be reduced by maintaining a local cache.
