Spam blocking

I get something like a hundred junk emails every day, so I use a homebrew setup employing procmail, spamassassin and just a drop of Perl glue, to bounce the rubbish back where it came from. Spamassassin is extremely good at what it does, but ultimately it's only heuristics, and it sometimes drops a legitimate mail. If you've come here because I've bounced your mail, this is how to get around it:

Start the Subject of your message with: [Notspam: 254c57ec]

Each code works for a limited period of time, but you should be alright once you've got the first mail through.
