Have you look at graylisting, temp failing mail with a sender/receiver/IP
you have not seen before?
I don't know what the prevailing attitude is, but it seems to me
that 451ing unknown senders is a good way to get on the bad side of
sysadmins who have to deal with the backlog until your server decides to
accept them.
Well every valid to/from/ip gets thrown in mysql any new message with that
same to/from/ip would never be delayed again. Also I temp fail before the
DATA phase so body is not sent twice and I only temp fail for 5 min.
How's that working? Many complaints? How much spam did it kill (that other things don't)?

Thought about changing it from to/from/ip to from/ip?
