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...


that's not strictly true. I'm considering SPF because of all the postmaster-bound back-scatter from stupid penny-stock Spammers that abuse one of my domains.
