Item used to send emails. The Sink.Smtp item will automatically use TLS if the server supports the STARTTLS command.
The Sink.Smtp item type has the following properties:
| Name | Description | ID | Flags |

| AuthenticationMethod |
Set smtp protocol specific authentication method (PLAIN, LOGIN, NTLM). This setting only has effect if username is specified. The PLAIN method sends the username and password in plain text. This method is straightforward but should always be used with an encrypted connection (like SSL/TLS) to protect the credentials from being intercepted. The LOGIN method also sends the username and password in plain text but in a slightly different format compared to PLAIN. The credentials are Base64-encoded, which is not a form of encryption but a way to encode the data. NTLM (NT LAN Manager) is a challenge-response authentication protocol used primarily in Windows environments. It provides a more secure method of authentication by not transmitting the password directly over the network. For advanced users, a custom authentication method can be defined using the format AUTH=method. |
