we have been on such situation where viruses catched some of our email
addresses and start spreading at great scale. The real problem which
make our servers really busy was to deal with bounces sent by antivirus
to that forged address, but we never had any problem with callouts. We
still receive some bounces for that addreses (which were deactivated
long time ago) and in fact we would prefer that other people use
callouts to avoid receiving such bounces, as handling callouts is more
efficient that having to deal with the whole bounce.

In fact any callout that you receive is another bounce that you avoid
receiving, so if you ever faced that situation you will really prefer
callouts than bounces.
