Bro weird, email notification

Hi, I need help with email notifications. I configured email server using ssmtp and put

hook Notice::policy(n: Notice::Info)

{

add n$actions[Notice::ACTION_ALARM];

}

to local.bro. Emails works fine, I recieve for example alarm summary, connection summary bot not weird activity and I see in bro.log that I have it in my network. What should I change or add?

Thank you very much!
