I, too, have been getting hammered with lots of bounces from spoofed messages using my domain(s). Unfortunately, I don't know if either of the things you proposed (SPF and Domain Keys) would make a difference here. The bounce messages are coming from the poor recipients of the spam, and at that point the message has already been bounced-- SPF and DK are really intended to "validate" legitimate messages. If the receiving mail servers were using them, you wouldn't be seeing the bounces because they would have already blocked/filtered the spam. That being said, it may not be a bad idea to look into implementing one or both of those solutions IF your domain is sending legitimate messages to customers or whatever. At least you'd boost your chances of that mail being received successfully. Like you, I think SPF is both good and bad, and DK is fairly complicated. $0.02, Jeff
