[On the SPF getting-towards-a-flame-war]
The problem is that SPF works fine if you look at it from the
perspective of an individual (with clue) - I know how my (legitimate)
mail gets to me, and can allow for that (so stuff thats being
legitimately forwarded via my vanity account with the federation of
yorkshire jelly wrestlers can be allowed for).
If you are a big provider (ie you are dealing with mail for 6 or more)
then any of your users can have random forwarding, everyone has to have
awful hacks like SRS to work round that (probably in the process making
themselves some form of open relay). So legitimate mail breaks.
Meanwhile the spammers have heard of SPF and mark their mail up
appropriately. In fact for a good while having a sender domain with SPF
data attached to it was a really effective marker of spam.
