Unified SPF

For those technically inclined, I found an intersting presentation of the possible next step about SPF, known as unified SPF : http://spf.pobox.com/slides/unified%20spf/. Good reading.

More details about SPF in the previous months news.

You can check at the SPF registry.

Some numbers

Statistics (beware, they may change from one year to another) I could collect from my own mailbox. Of course, I receive more SPAM than most, but these statistics are probably significant anyway.

• 200 SPAM per day (it was reduced recently when I closed a domain that no longer hosted more than SPAM traps).
• 12% of all SPAM is found using filters I set using the black list at SpamAnti.net.
• About 30% are catched by a manual filter in Pegasus Mail - my email reader (e.g. detecting the presence of [ADV] in the email subject line).
• K9 allows to include some manual filters (not statistics based). This conservative configuration catches 48% of all SPAM messages.
• K9, my bayesian filter finds nearly all SPAM (99,88% success rate - includig the manual filters).
