[Bro] SSH brute-force email notice

Thank you for your answer.

I have checked the logs during my scenario and when the email doesn’t send nothing get logs at all (not even on the bro stderr log). However, when I raise a dummy notice in a bro_init() event, then I receive the email and the email gets logged properly.

Note that I am using macOS Sierra so I access my logs through the following command `log stream --predicate  '(process == "smtpd") || (process == "smtp")' -info`.

Any idea of what could be the problem ?

Thanks again,
