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
