Hi,
The default without anything configured is to email alerts to the device's sysContact.0. This is probably what's happening.
I've added a new alert transport called devnull in r9573 which will pretend it sent something, but won't.
If you add this to the alert entry, it'll suppress the defaults.

I’m trying to configure emailing so that I would like to be notified on some alerts generated by some of the alert checkers but not all of them, but I’m not able to do it L Currently I’m receiving email alerts from all of my checkers. This is my current “config.php”: // Set up a default alerter (email to a single address) // $config['email']['default'] = ""; // $config['email']['default_only'] = TRUE; $config['email']['from'] = "< I omit this part, this is our current email, this is working >"; $config['email']['smtp_host'] = "< I omit, our SMTP email server >"; $config['email']['backend'] = "smtp"; // Mail backend. Allowed: "mail" (PHP's built-in), "sendmail", "smtp". $config['email']['smtp_timeout'] = 30; We have only one contact with our destination email address and we have associated only 4 of 7 defined alert checkers, but we are currently receiving email notifications from all of them.
