Cyren Antispam in cluster setup
Question asked by WebControl GmbH - August 9, 2016 at 6:54 AM
Hello community and team,
we're using SmarterMail with four incoming gateways and one central MDA. The central MDA installation is licensed with a unlimited SmarterMail Enterprise Edition. The incoming gateways running without license key as free edition.
Now we added "Cyren Premium Antispam" to our license. Obviously, the best practice would be to let the incoming gateways do the antispam work.
For understandable reasons using the same key on multiple instances is prohibited by SmarterTools. But is there a workaround or solution for this kind of cluster setup?     
Thanks and kind regards,

I agree that it would be nice to offload the antispam work to the gateways. Here's a thread where I suggested scoring Bayes & Cyren on the primary, and then adding that to the score coming from the gateway:
There may be other ways to solve this as well.

Hi Viktor,
It is not currently possible to use Cyren Premium Antispam on a gateway server, and I believe this is a limitation put in place by our licensing agreements with Cyren. There is an older thread where users discussed this, and one mentioned reaching out to Cyren directly for their answer. You can review that if you'd like here: https://portal.smartertools.com/community/a575/cyren-licensing-on-incoming-gateways.aspx
I hope this helps.
