Greylisting is the #1 standard for spam filtering.
- spc476 11y agoUm ... maybe. I run a greylist daemon and I wrote about its effectiveness a few months ago (http://boston.conman.org/2015/04/12.1 http://boston.conman.org/2015/04/12.1), which also goes into how effective SPF would be had I actually used it in accepting incoming email. I also wrote about the effectiveness of the various blacklists out there as well (http://boston.conman.org/2015/05/11.1 http://boston.conman.org/2015/05/11.1).
