Autoresponder is bad idea. You need better heuristics than what procmail
can do.
I gave up long ago on sending back "remove" requests. Now I simply force
procmail to exit with an error when it detects probable spam. This means
that the spammer gets a "permanent" delivery failure -- if a message is
sent, it's sent by sendmail as a daemon message with a null return-path,
so it can't bounce back again. This has actually been quite effective in
getting my name off spam lists, if the number of spam-rejections logged by
procmail is any indication; it has been steadily decreasing.
Of course, I also save a copy of most of the messages and check through
that mailbox occasionally to be sure my filter is accurate, so that I can
respond manually to any mail I might really have wanted to see.
