Message Sniffer Subscriptions

Subscription Information

All Message Sniffer subscriptions include:

We will provide you with a single Sniffer license ID that identifies your specific rulebase for all of your authorized instances. You will be able to use this rulebase on as many systems as you require, provided you have purchased the correct number of instances (typically, one instance per MTA).

How many subscriptions (authorized license instances) do I need?

You will need one authorized instance for each copy of Message Sniffer you will be running on your equipment. Special provisions can be made for active standby/failover instances provided those instances do not carry production traffic. Note: Backup MTAs usually require their own instance because they actively process production traffic and are a favorite target of spammers!

We can provide additional license IDs in special cases where different rulebase versions are required for different instances. Please contact our support department for details.

For more information about subscriptions, please visit the Q&A section.
