SPF
No, not sunblock. SPAMblock. Presented here for personal reference.
Some forum. Update: Oh crap does that forum ever suck. You click through and can read, and then the next time you click through, it asks you for money. Grr.
A basic rundown, which includes a nifty chart.

I’ve spent the better part of the evening cleaning some nasties off my machine. Security Task Manager was very helpful there. But thats on my Windows machine.
There’s a tutorial? LOL I’m afraid to click on that. Chicken Me.
SPF solves a very specific problem, and if that’s not the problem you have, it’s better not to use SPF to solve it.
Basically: The way email works, anyone can spam with return addresses pointing back to your domain name. So you set up an SPF field in your domain name’s DNS record, and mail servers can check your domain’s SPF to see if mail that claims to be from your domain name really is.
I’m researching this because I got about 800 bouncebacks today, all from spammers using my domain name.
Dang, so much for my freepr0n@homersdomain.com campaign.
