Suppose I own cluebytwelve.com (I do), and I want to send mail "from
sethb(_at_)cluebytwelve(_dot_)com" from my home computer. I can set up an SPF
record for cluebytwelve.com to specify that my current IP address has
that permission, completely independent of the ISP that provides
IP-level access. That works well for me, even though the ISP doesn't
authorize my home machine to send directly email from "sethb(_at_)ISP".
I suppose there's nothing preventing DynDNS etal from extending their
current dynamic DNS service to offer SPF records.
Technical question; does SPF authorize an IP address, a forward DNS,
or an rDNS to send email for a given domain?

Email users are divided into two classes;
1) Those who have effective spam-blocking
2) Those who wish they did
