I just configured an E-mail notification.

Configuration -> Centralized Message Logging

Send log message via E-mail if severity is Information and above.
From - [my internal e-mail address]
To - [my internal e-mail address]
Subject %s [%t]: %d %c

Configuration -> SMTP Settings

SMTP Server Address [internal SMTP server IP address]
SMTP Port 25

But I didnt receive anything .
There are no connections to e-mail server from ZCM server.
How to turn on notification by e-mail?
