Is the problem that such emails go to users' mailbox and are not quarantined?

No, these messages are redirected to Spam folder with [sPAM] tag but they are not spam

Hello Ivart,

 

the message has score 81, but we quarantine only messages with score above 90 with default settings. 

Have you modified it?

 

Which version of EMSX do you use?
