I love the idea, and just put SPF records in all my domains. Not like I
have a lot of users (just me and the wife!), but I've noticed lately a
lot of bounces from spammers forging email address from a couple of my
domains, and this *may* cut down on some of those.
Next step - start using SPF filtering to reduce spam. As soon as I get
qpsmtpd working :)
I can't wait until everyone fixes SMTP everywhere so I don't have to
resort to challenge/response spam killing like I do now. Probably what
I'll do for now is let in everything which gets a "pass" from SPF, and
challenge all "unknown"s and "fail"s. Maybe eventually I'll start
dropping all "fail"s.
Keep up the good work and advocacy. I'd love to see
aol/excite/yahoo/hotmail/microsoft/wanadoo.fr (and my own ISP, too!)
implement this :) I'm going to suggest to my two main local ISPs
(sasktel.net and shaw.ca) that they look into getting SPF going. I
suppose once they do I'll have to change how I do forwarding locally,
but that's okay with me.
