Product Summary
The Cyren Anti-Spam add-on for SmarterMail provides your mail server with improved spam filtering thanks to Cyren's Recurring Pattern Detection (RPD). This means spam, phishing attacks, and other scams are blocked from your inbox in real-time. This product is available for both Professional and Enterprise versions of SmarterMail.
After your purchase we may issue a pro-rata refund. This is so that we can bring into line all your Add-on and Upgrade Protection renewals to the same date.
