Sendmail Question

[st0rmchaser]

I want to have users receive email but also have a catchall. To clarify, I'd like to receive my mail but have garbage go nowhere so it doesn't bounce and notify spammers what might be on my system. How do I go about that?

Thanks.

I think Sendmail milter is what your looking for.
