How to handle returned mail?

[Joe D'Andrea]

Q: When email is returned to sender, is this bounce also added in to the
wordlist hopper? Should it be exempt?

I'm not sure what the most appropriate plan of attack is. For example, I
just bounced several messages to uce at ftc.gov and the server happened to
bounce them back (which usually never happens).

Some of those bounces landed in my inbox, and others landed in my spambox!
So now these messages also have elements of the original UCE. Hmm ...

Do I remove them from both the spam and nospam wordlists? Just the nospam?
Just the spam?
