Actually, this usually opens up a one of my most popular can of worms...
An entertaining pastime is in trying to make spam-autoreply systems
experience a mail-meltdown :-).

If their autoreply system is sufficiently deficient in setup, one might
be able to trick it into autoreplying to itself.  There are several ways
to do this, of course, depending on the level of sophistication of
the autoreply daemon.  Suffice it to say that properly setup procmail
autoreply setups cannot be fooled.
