Is there a way I can ratelimit messages on sender id.

Off late I have seen that my spamtraps are being thrashed by random
yahoo or hotmail sender (forged ) mails .. all identical fake pharmacy
spams.
Infact I get upto 300 connections a minute for a singe mailbox and that
takes up all the smtpd processes on the machine


I tried blocking the from id and the spam-bot changes the id in the very
next hour


Is there a way I can auto ratelimi mails on from-id

Thanks
Ram
