+# Email
+
+You need a working `sendmail` command for email alerts to work. Almost all MTAs provide a `sendmail` interface.
+
+Netdata sends all emails as user `netdata`, so make sure your `sendmail` works for local users.
+
+email notifications look like this:

+
+## configuration
+
+To edit `health_alarm_notify.conf` on your system run `/etc/netdata/edit-config health_alarm_notify.conf`.
+
+You can configure recipients in [`/etc/netdata/health_alarm_notify.conf`](https://github.com/netdata/netdata/blob/99d44b7d0c4e006b11318a28ba4a7e7d3f9b3bae/conf.d/health_alarm_notify.conf#L101).
+
+You can also configure per role recipients [in the same file, a few lines below](https://github.com/netdata/netdata/blob/99d44b7d0c4e006b11318a28ba4a7e7d3f9b3bae/conf.d/health_alarm_notify.conf#L313).
+
+Changes to this file do not require a Netdata restart.
+
+You can test your configuration by issuing the commands:
+
+```sh
+# become user netdata
+sudo su -s /bin/bash netdata
+
+# send a test alarm
+/usr/libexec/netdata/plugins.d/alarm-notify.sh test [ROLE]
+```
+
+Where `[ROLE]` is the role you want to test. The default (if you don't give a `[ROLE]`) is `sysadmin`.
+
+Note that in versions before 1.16, the plugins.d directory may be installed in a different location in certain OSs (e.g. under `/usr/lib/netdata`).
+You can always find the location of the alarm-notify.sh script in `netdata.conf`.
+
+## Simple SMTP transport configuration
+
+If you want an alternative to `sendmail` in order to have a simple MTA configuration for sending emails and auth to an existing SMTP server, you can do the following:
+
+- Install `msmtp`.
+- Modify the `sendmail` path in `health_alarm_notify.conf` to point to the location of `mstmp`:
+```
+# The full path to the sendmail command.
+# If empty, the system $PATH will be searched for it.
+# If not found, email notifications will be disabled (silently).
+sendmail="/usr/bin/msmtp"
+```
+- Login as netdata :
+```sh
+(sudo) su -s /bin/bash netdata
+```
+- Configure `~/.msmtprc` as shown [in the documentation](https://marlam.de/msmtp/documentation/).
+- Finally set the appropriate permissions on the `.msmtprc` file :
+```sh
+chmod 600 ~/.msmtprc
+```
