Feel free to bounce as much spam forged with my return address as you
like, so long as you first follow at least the bounce suppression
criteria I do:

No bounce if the message claimed to be from a mailing list.
No bounce if the spam scored higher than 8 in spamassassin
No bounce if the server which you received the spam from doesn't match
my domain's published SPF records evaluated as if "~all" and "?all"
are "-all"
