Well, I don't really know Amavis, so I don't know what this does
precisely, but in general...
Bounce, also known as backscatter in the context of spam -- just in case
you need more search terms. ;)
The important difference is, that REJECTing on the MX (the outside, evil
network facing SMTP) will just not ACCEPT the message. Once you accepted
a message, you take responsibility for it. You are free to review that
crap, or even route it straight to the bin bucket. It's yours, and the
ball is on your side. However, bouncing it "back" to some address you
cannot possibly know is the real sender...

Thank you for fixing this. :) One less backscatter source on the net.
