Re: Response to DDoS using SPF2005-03-24 03:13:53"David MacQuigg" opined: Simply removing SPF may not be an option. More likely there would be a worldwide switch to SenderID [... ,] which avoids all these problems. SenderID uses the same record syntax and DNS look-up system as SPF. It is, I suspect, therefore vulnerable to the same kind of DDOS attack, with the same potential for amplification. Chris Haynes
