That was entirely not the point of SPF though.
(rest deleted for brevity). All true, but the bottom line was that at some stage you could highly correlate between finding an SPF/senderId record and figuring that you are dealing with a spamming domain. But anyway, it's almost a theoretical discussion - even with Hawards numbers not contradicting this, I'm pretty sure it's not practical to do much with this info beyond maybe being able to more tightly bind the negative reputation of a spammer to the domain/id he used to send the spam from. --Amos -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
