How can I make my MT stop viruses from coming into my network? There are some hardware that do this but are very expensive. Can MT do this? Check and stop viruses?
Hi, i created these 2 simple rules for firewall forward and this work very fine...... do not say it to anybody
2 ;;; BLOCK SPAMMERS OR INFECTED USERS
chain=forward protocol=tcp dst-port=25 src-address-list=spammer
3 ;;; Detect and add-list SMTP virus or spammers
chain=forward protocol=tcp dst-port=25 connection-limit=30,32 limit=50,5 src-address-list=!spammer action=add-src-to-address-list
When detect an infected user with a worm or doing spamming this rule add this user to a spammer list and block the STMP outgoing for 1 day
