Mail to non-existent users should bounce, so that people know the email
wasn't delivered.

Almost invariably sending email to /dev/null is a mistake (or at least a
last resort).

I'm not quite clear what your problem is - if you mean that it goes into
the outgoing mail queue on DMZ and stays there because the senders
address is spoofed - that is okay it should automatically time out of
the queue eventually (although I have a sendmail install that doesn't do
this reliably at work as well - time to go Postfix!).

Most MTA have a system so that such double bounces can be sent to the
bitbucket - which is one of the few exceptions to my earlier comment.

Most email is spam these days, so it is hardly surprising most lost
emails are spam. Doesn't mean you shouldn't stick with the documented
SMTP behaviour - the guys who wrote the standards weren't completely
stupid even if they didn't anticipate 100's of 1000's of compromised
Windows PCs sending spam.
