Annual Subscription

Message Sniffer is available as an annual subscription for less than 2 dollars a day. A $495/year subscription connects you to Message Sniffer's advanced spam filtering database, which is maintained and updated around the clock by examining and categorizing unsolicited commercial Email messages, pornography advertisements, and other unwanted content.

The Message Sniffer subscription includes:

• All Message Sniffer software updates
• Rulebase updates multiple times a day with the latest anti-spam rules
• Full support for your subscription year, including personalized support for tuning and customizing rulebase(s) to fit the needs of your system.

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 to 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 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).

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.
