Enable an Email Server

The SMTP email server must be configured to enable email and SMS notifications and digests to be sent by the Controller.

Permissions

For this activity, users need the predefined Account Owner role or another role with the Configure Email / SMS permission.

Configure an SMTP server

In the Controller UI, from the top navigation menu bar, click Alert & Respond > Email/ SMS Configuration.
Provide the connection information for the SMTP host and port.
Use a host and port settings for an SMTP server available in the controller deployment environment.
Customize sender address in notifications emails in the From Address field. By default, emails are sent by the root Controller user.
If the SMTP host requires authentication, configure the credentials in the Authentication settings.
If you want to add any text to the beginning of the notification, enter it in the Notification Header Text field.
If you are using SMS do one of the following:
- Select Default and choose one of the available carriers from the pulldown menu.
- Select Custom and enter the phone number receiving the message as <phone number>@<sms gateway>.
  For example, a mobile phone in the United States serviced by AT&T might be:
```
4151234567@txt.att.net
```
  A mobile phone in the United Kingdom serviced by Textlocal might be:
```
7412345678@txtlocal.co.uk
```
  See SMS gateway by country for information on most common SMS gateways.
Test the configuration by sending an email.
Save the settings.

After the email server for an on-premise controller is enabled, we recommend changing the admin user email from the default email for heightened security.

Troubleshoot Notifications

If you do not receive notifications for health rule violations, it could be because the default SMTP server timeout period is too short. To troubleshoot, increase the value of the mail.smtp.socketiotimeout Controller Setting in the Administration Console. The default value is 30 seconds.
