I really like the Sender Permitted From mechanism (http://spf.pobox.com). It allows you to designate which hosts are permitted to send mail from domains which you control. You can also check incoming mail to see if the sending domain has specified SPF and, if so, if the mail is coming from an authorized host. It's not widely adopted yet, but if and when it is, it could put a big dent in spam, since most of it has forged addresses. I'm encouraging everyone I know to implement it.
