Agreed...

I am looking into SPF plugin for SA now. Does anyone know how it 
handles domains with no SPF record? I would assume that if no SPF 
exists, then forgeries are not penalized for that domain. Just need to 
make sure before I turn this plugin "ON" in production.

One other thing (feel free to email me off list), what is the 
difference between Sender ID and using SPF records? Or are they the 
same thing.... I like SPF, I like the fact that you control it within 
your own domain via your DNS server. When I hear Microsoft talk about 
Sender ID I get nervous, I envision some type of paid subscription to 
be listed on some central repository that Microsoft controls!
