While on the subject of preventing spam, could someone please share horror/success stories of using Sender Address Verification [ala callbacks in Exim] before accepting mails?
Some people seem to like it. But speaking as a provider whose domains are very often forged into spam, I would say "don't use callbacks - it puts a huge load on such domains".
I do this, but only after my blacklists and whitelists are covered. Regular correspondents are whitelisted. New people get a check. Minimise your expensive checks.
That seems like a good approach. Are the whitelists maintained automatically?
