That's an answer, but the OP still has not figured out what the question
is, so he should do nothing until the question is understood.
In most cases, discarding mail to invalid addresses is unwise, the
address could be an honest typo and the message may be important.
If the concern is dictionary attacks, just use a sensible postscreen
configuration to keep the bots away or accept the fact that one can't
keep email addresses secret, focus on stopping spam, not hiding email
addresses.
