Filtering policy

I have unfortunately long ago reached a point where the amount of unsolicited commercial (spam) and virus e-mail exceeds the regular e-mail messages I get.

That's why I've implemented mail filtering.

Recently I have deployed bogofilter to filter my e-mail.

This has proven to give fewer false positives than my previous home-grown procmail based solution. I have configured bogofilter to categorize mail as either non-spam, unsure or spam. Mails in the unsure mailbox will be evaluated by me and used to further train bogofilter.

Other bogofilter users can mail me if they would like a copy of my wordlist.db file.

After having trained bogofilter for a couple of weeks, it is now filing spam automatically to where it belongs: /dev/null.

If you send me HTML formatted mail, the chances of getting caught in my spamfilter increase, because spammers use HTML mail a lot. So if you can't reach me, please try sending your mail as plain text. (Instructions for doing so with outlook express here, and for outlook here.)

If you are using outlook or outlook express, you're inviting trouble. These programs have over the years proven to be an easy way for viruses to infect and use your computer. You would be wise to look for alternatives.
