Just as easy, because in the SMTP session, you specify:

RCPT TO: <[EMAIL PROTECTED]>

and then you can put whatever you darn well please in the body.  The #1 most
effective spam filter is to add a procmail rule that dumps anything *not*
specifically sent to your address into a "spam" folder.  I have a catch-all
rule at the end of my .procmailrc:

:0:
* !^(to|cc):.*(soren|stharward|sth22)@.*byu\.(edu|net)
.spam/

That's the extent of my spam filtering, and it works wonderfully well.
