I host my own email, and a few domains for my family. A few weeks ago I finally added SPF records to my DNS servers in hopes remote mail servers will stop marking emails from my servers as spam. On the flip side, I've used TMDA for years, as well as DNSBL, to reduce the amount of spam that gets into my inbox.
Recently I enabled the qmail SPF patch, set spfbehavior to 3, and added this simple rule to my TMDA filter:
headers 'Received-Spf: pass.*' okThis hopefully will do two things:
Reduce the amount of trash TMDA should respond to, and subsequently reduce indirect spam from my domain (via bouncing to forged senders). This is predicated on more mail providers adding SPF records.
And make it 'easier' for new people to send me email, reducing the chance I miss their email, especially if their mail server marks my challenge as spam and parks it somewhere out of sight.
