I do already see spammers smart enough to retry addresses from

My prediction for next 200 days is that most spammers get the clue,
but it gives us perhaps 3 months of less leaked junk.
Great!
IMHO this is only an step in an "arms race".
What you will do in three months, remove this check because it will
prove useless since the spammers will also retry ? If yes, why install
it in the first place ?
Why ever do anything? You're going to die eventually anyway...
Right! The problem here is that it may do more harm than good.
May I suggest a smarter way to filter these spammers, by just whitelisting
email addresses of valid posters, after sending a confirmation for the first
post. Now if these spammers get smart, and start using personal email
addresses, I would certainly expect some real action by abused email address
owners.
So a challange to the kernel hackers: build a mail filtering/proxy
system, a' la BSD.
I don't remember the specification and features, but IIRC the
netfilter is not enough to do the graylisting (but pf was).
Someone has some hints what kernel can do in the fight against
spam?
