Hi everyone,

Since I migrated my SmarterMail server to a new machine, Cyren has become unusable for me. I haven’t been able to reactivate the license, and although I opened a ticket, it looks like the issue is on Cyren’s side.

For the last 7 days my logs have been full of entries like these:

[2026.10.19] 12:03:42.083 [98260945] [CyrenIP Client] Cyren Error: Could not scan, No enabled services provided by Cyren based on license key.
[2026.10.19] 12:03:42.799 [98260884] [CyrenIP Client] Cyren Error: The operation has timed out.
[2026.10.19] 12:03:42.800 [98260927] [CyrenIP Client] Cyren Error: The operation has timed out.
[2026.10.19] 12:03:42.825 [98260941] [CyrenIP Client] Cyren Error: The operation has timed out.
...

This morning I also noticed that the timeouts were slowing down spam checking significantly, so I’ve disabled both Cyren IP and Cyren Anti-Spam entirely.

I’ve been watching SpamFoo for a while and it looks quite reliable. For now I’ve given it a low weight (2).

A few questions:

• What weight have you set for SpamFoo?
• Is anyone already running it in production, and how is it performing?
• Has anyone else had Cyren license issues after a server migration?

To be honest, without Cyren I haven’t noticed much difference in spam detection so far. I still have Message Sniffer, RBLs, greylisting and the other tools SmarterMail provides.

Thanks in advance for any feedback.
