I am currently testing Cyren on one of my Smartermail installations. I am liking it very much.
I would like to know if it is possible to license it to be used on Incoming Gateways.
For example, I have 4 Smartermail servers. I would like to make a new server to act as the Incoming Gateway for all my servers, where I would eliminate most Spam before delivering it to the e-mail servers (and archiving it, wasting valuable space storage).
How would I license it? As far as I know, Smartermail can be used as a Incoming Gateway for free. How would I license Cyren? As unlimited accounts?
