Nowadays, every sicko can buy a .com domain for 9$ or even less.
Spammers buy domains, put correct SPF records in their zonefiles and
throw the domain away afterwards... (just like you did with hotmail
accounts a few years back :-))
So IMHO DNS based spam fighting doesn't work. At least not the SPF way...

And why not using the existing authentication protocol on outgoing smtp
server ? So the sender can use the smtp server of the provider of its
email address from any network and SPF can work without any problem.
Did i forget anything ?
