Customizing Mail Delivery
One advantage to using an SMTP connector for outbound mail, instead of using an SMTP virtual server, is that you can specify additional configuration settings to affect how mail is delivered. Whether you must adjust the default values for these settings depends on how you want your SMTP connector to deliver mail.
Additional configuration settings for an SMTP connector
| Settings | Description |
|---|---|
Delivery restrictions |
Restricts who can send mail through a connector. By default, the connector accepts mail from everyone. You configure these settings on the DeliveryRestrictions tab of the SMTP connector's Properties dialog box. |
Content restrictions |
Specifies what types of messages are delivered through a connector. You configure these settings on the Content Restrictions tab of the SMTP connector's Properties dialog box. |
Delivery options |
If you connect to a network service provider to retrieve your mail, configure a connector to run on a specified schedule, and implement advanced queuing and dequeuing features. You configure these settings on the Delivery Options tab of the SMTP connector's Properties dialog box. |
SMTP communication |
Controls how the connector uses SMTP to communicate with other SMTP servers. Specifically, you can specify whether the connector uses SMTP or Extended Simple Mail Transfer Protocol (ESMTP) commands to initiate a conversation with another server and control the use of the ERTN and TURN commands. (These commands request that another SMTP server sends the e-mail messages that it has.) You configure these settings on the Advanced tab of the SMTP connector's Properties dialog box. |
Outbound security |
Ensures that any mail flowing through the connector is authenticated. This setting is useful if you want to establish a more secure route for communicating with a partner company. With this setting, you can establish an authentication method and require Transport Layer Security (TLS) encryption. You configure these settings on the Advanced tab of the SMTP connector's Properties dialog box. |
