hi is there any harm in using ip tables to limit connections per second or per minute to the qmailtoaster mail server to ward off spammer.
iptables -I INPUT -p tcp --dport 25 -m state --state NEW -m recent --update --seconds 30 --hitcount 10 -j DROP has anybody tried this ? recently i a rogue mailing list server sent one of my customer's email id over a hundred emails in just a couple of seconds repeatedly to the same email id with each one being a separate email. In just around 5 mins i had thousands of these news letters in my queue. The issue was probably because spamdyke was accepting connections only after around 6 seconds by which time the mailserver used to time out and resend. rajesh --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
