Comments on: Who are the Earliest Adopters of SPF? Survey says: Spammers! http://www.theinternetpatrol.com/who-are-the-earliest-adopters-of-spf-survey-says-spammers Internet Safety, Windows Updates, Internet News, and More Sat, 22 Nov 2008 02:23:08 +0000 http://wordpress.org/?v=2.6.3 By: Kelson http://www.theinternetpatrol.com/who-are-the-earliest-adopters-of-spf-survey-says-spammers#comment-299 Kelson Wed, 01 Sep 2004 09:15:56 +0000 /?p=87#comment-299 The article neglects to mention another set of early adopters: sites whose domain names have been repeatedly forged in spam. I handle the email abuse reports for my employer, and for the past year I've gotten several complaints a week. To date, not a single one has been over a message that actually came through our network or from our customers. We put up SPF records last December, but since hardly anyone checks them, it hasn't stemmed the tide of misdirected complaints. Another missing piece of information is the percentage of email that actually *fails* SPF checks. So they found that 3.8% of spam passes and 2.8% of legit mail passes. That's disheartening, but SPF is pass/fail/neutral, not just pass/fail. What if 10% of spam *fails* and only a tiny amount of legit mail does? If that's the case, then it's already proving useful. But without those numbers, there's no way to tell. The article neglects to mention another set of early adopters: sites whose domain names have been repeatedly forged in spam.
