I use procmail in conjunction with a "stealth address" (i.e. a second mail
address from one of those free forwarding providers) which I only use for
mailing lists and usenet) to bounce everything back which arrives via that
address without being addressed to that address (i.e. the To: od Cc: lines
do not contain my "stealth address"). In addition, I have a "whitelist" for
my friends addresses to make sure their Bcc mails arrive unharmed and to
exempt mailing list mails from that rule (obviously...).
Over the past months, that combination had a success rate of 99%, i.e. all
bounced messages were indeed spam except for one (where I forgot to add it
to the whitelist...). None of the bounced mails bounced back to me.

Just my =A30.02,

Thomas
