We have many partners that have integrated our product in various ways. Our first advice would be for you to keep using the Imail integration of Commtouch.

If you would like to place something in between the internet and Imail, you would need to deploy a gateway. We have some partners that offer such solutions. However, the IMail deployment also provides IP Reputation that should be dropping lots of threats at the perimeter.

The only way to use Commtouch directly (as a Gateway) is to use our Enterprise Gateway solutions that runs only on windows. It offers real time spam filtering as well as zero hour virus outbreak detection (no IP Reputation). This enterprise solution is offered through our reseller channel.
