In this month's VBSpam test, spam catch rates were high, but false positives were still an issue for some products - two of which failed to achieve a VBSpam award. The introduction of a slightly modified formula for calculating products' final scores has made achieving a VBSpam+ award a little harder - yet four products managed to do so.

VBSpam comparative testing is a regular independent comparison of anti-spam solutions.
The aim of these tests is to offer readers the best impartial advice about anti-spam security and the products on offer.
By using a combination of two live spam streams representing mailboxes all over the world, as well as a live stream of legitimate international emails, the VBSpam test aims to reflect the experience of a real end-user as accurately as possible.
VBSpam certification is awarded to products that exceed a predefined threshold based on a combination of criteria relating to the products' spam catch rate and false positive rate.
To display the VBSpam verified logo, an anti-spam solution must be capable of:
- blocking a large percentage of emails in a live spam stream
- correctly identifying all but a very small percentage of emails in a live stream of legitimate emails.
The detailed test methodology can be found here.

Spam is changing continually, both in quality and quantity, and to protect inboxes and networks an anti-spam
solution must be able to keep up with these changes.
An archive of VBSpam test results is available, allowing users to view the performance of a vendor or solution over time.
While a single test can only show a snapshot of a product's capabilities at a specific moment in time, this long-term
view can be used as a guide to how vendors are likely to perform in future. Listings of results by product are here.
VBSpam results chart
The VBSpam chart allows at-a-glance comparison of product performances, plotting spam catch (SC) rate against false positive (FP) rate. The better performing products will appear in the top right-hand corner of the chart, with the highest SC rate and lowest FP rate.
