Flow Guard

Flow Guard ermöglicht es, die Menge an ausgehenden E-Mails zu kontrollieren. So können ungewollte Massenmails – seien sie nun von unbedarften Benutzern erzeugt oder durch Malware ausgelöst – vor dem Versand erkannt und die Reputation der eigenen Domain geschützt werden. Dazu weist Flow Guard den NoSpamProxy-Benutzern Kontingente für ausgehende E-Mails zu. If the set threshold is exceeded, any further outbound email is rejected.

There are a total of two threshold values that can be set per user:

  • Number of emails per hour
  • Total number of emails per day
TIP: You can also assign the thresholds based on AD group memberships.
