Rate Control
- Click the 'Rate Control' tab in the SMTP IPS/FW module.
- The 'Rate Control' feature protects an organization from spammers that send huge amounts of mail to your mail server.
- It counts the number of suspicious mails sent by a source in a set period of time. If the value exceeds the specified threshold then the sender IP is added to the blacklist.
