ESMTP Settings

Use this property page to configure the Extended SMTP (ESMTP) settings for the GroupWise^® Internet Agent. These are settings that might or might not be supported by another SMTP system.

Enable Delivery Status Notification
Turn on this option to allow the Internet Agent to request status notifications for outgoing messages and to supply status notifications for incoming messages. This requires the external e-mail system to also support Delivery Status Notification. Currently, notification consists of two delivery statuses: Successful or Unsuccessful.

DSN Hold Age
Select the number of days that you want the Internet Agent to retain information about the external sender so that status updates can be delivered to him or her. For example, the default hold age causes the sender information to be retained for 4 days. If the Internet Agent does not receive delivery status notification from the GroupWise recipient's Post Office Agent (POA) within that time period, it deletes the sender information and the sender does not receive any delivery status notification.
