Monthly Subscription

Message Sniffer monthly subscriptions are available for $45/month/instance. Monthly customers are billed on the 5th of each month. If you sign up in the middle of the month, you first month will be prorated.

In the event you should need to cancel your subscription, please give 15 days written notice to billing@armresearch.com.

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.

If you are adding a new server to your setup, please contact the billing department to authorize an additional license instance and to update your monthly billing information.
