FastNetMon e-mail notification

FastNetMon can send emails about hosts blocked using blackhole approach and it can send emails about each partial block rule (BGP Flow spec mode) deployed to block malicious traffic.

We recommend using SMTP server in your network to avoid issues during DDoS attacks because external connectivity may be affected by attack and email notification will not be send.

In case of any issues with email delivery, please check that your server has application “msmtp” installed. Also, you may check /var/log/fastnetmon/email.log file about any error messages.

You also may change default email subects easily:
