You can send notifications by email, using an SMTP server of your choice. Once you have configured the email target, you can specify the recipients, and customize the subject line and message content.

General Settings

​

Target ID: Enter a unique name to identify this email notification target.

Configuration

​

Address: Identify the SMTP server by its hostname or IP address.

Port: Set the SMTP port. Use port 587 for SMTP Secure (SMTPS). You can also use port 25. Use 465 when SSL/TLS is enabled. You can also use port 2525 if your email service provider supports this port as a backup when other ports are blocked by a network provider or a firewall.

From: Identify the email address of the sender.

Encryption type: Specify the encryption type used to secure SMTP communication. Options include:

• STARTTLS: Select this option to start the connection as plaintext, then upgrade it to a TLS-encrypted one if the server supports it. If the server doesn’t support it, the connection remains plaintext.

  STARTTLS upgrades the connection to be encrypted but does not authenticate the server. Take additional steps to prevent man-in-the-middle attacks.

• Require STARTTLS: Select this option to require TLS. If the server doesn’t support a secure connection, the connection will be dropped.
• TLS (SMTPS): Select this option to use an encrypted connection from the start without requiring a subsequent connection upgrade.
• None: Select this option to use a plaintext connection.

Minimum TLS version: Optionally, select the minimum TLS version to use when connecting.

Maximum TLS version: Optionally, select the maximum TLS version to use when connecting.

Validate server certs: Toggle on to reject certificates that are not authorized by a CA in the CA certificate path or by another trusted CA (such as the system’s CA).

Authentication

​

Username: The authentication principal (if required).

Password: The authentication credential (if required).
