Distributed SMTP Tracking
Keep track of successful SMTP logins (Postfix only). If the number of successful logins to an individual account is at least LF_DISTSMTP in LF_DIST_INTERVAL from at least LF_DISTSMTP_UNIQ IP addresses, then all of the IP addresses will be blocked. This option can help mitigate the common SMTP account compromise attacks that use a distributed network of zombies to send spam. A sensible setting for this might be 5, depending on how many different IP addresses you expect to an individual SMTP account within LF_DIST_INTERVAL. Be careful with this setting as if you have third party email services setup to relay email though your own server then their servers will get likly get blocked - e.g. if Gmail users are relaying though your server).
- Navigate to Juggernaut Firewall -> Settings -> Login Failure Daemon -> Tracking Settings -> Distributed Attack Tracking.
- Check the Distributed SMTP limit and set the desired Distributed SMTP trigger.
- Click the Update button to save your settings.
- Click the Restart button to restart the firewall and login failure daemon.
