KUMA can be configured to send email notifications using an SMTP server. Users will receive notifications if the Receive notification by SMTP check box is selected in their profile settings.
Only one SMTP server can be added to process KUMA notifications. An SMTP server connection is managed in the Settings → Notifications section of the KUMA web interface.
To configure SMTP server connection:
In the Resources section of the KUMA web interface, open the Secrets tab.
The list of available secrets will be displayed.
Click the Add secret button to create a new secret. This resource is used to store credentials of the SMTP server.
The secret window is displayed.
Enter information about the secret:
In the Name field, choose a name for the added secret.
In the Type drop-down list, select credentials.
In the User and Password fields, enter credentials for your SMTP server.
If you want, enter a Description of the secret.
Click Save.
The SMTP server credentials are now saved and can be used in other KUMA resources.
Open the KUMA web interface and select Settings → Notifications.
Make the necessary changes to the following parameters:
Disabled—select this check box if you want to disable connection to the SMTP server.
Host (required)—SMTP host in one of the following formats: hostname, IPv4, IPv6.
Port (required)—SMTP port. The value must be an integer from 1 to 65535.
From (required)—valid email address of the notification sender. For example, kuma@company.com.
In the Secret drop-down list select the Secret resource you created before.
Select the necessary frequency of notifications in the Monitoring notifications interval drop-down list.
Turn on the Disable monitoring notifications toggle button if you do not want to receive notifications about the state of event sources. The toggle switch is turned off by default.
Click Save.
The SMTP server connection is now configured and users can receive email messages from KUMA.
