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?

For each physical computer (MTA) where you run Sniffer you will need an authorized license instance. The rulebases will be identical for each server. If you add a special rule, it will be received in your rulebase update for all of your servers. In special cases, we can accomodate a second license id - please contact our support department for details.

Adding a new server? Please see the Additional License Instance page for more details.

How Do I Get Started?

1. Sign up for a 30-day FREE Trial. This will give you a production ready rulebase and updates FREE for 30 days. You need the rulebase to setup your SNF software. Our system will send you rulebase download instructions when your rulebase is ready.
2. Download a Message Sniffer software distribution that is appropriate for your system and set it up using your trial SNF license.
3. During or after your trial, purchase a subscription for Message Sniffer. Please note, purchasing a subscription before your trial is over will NOT cut into your free 30 days.
