When enabled, Message Disposition Notifications (also known as Receipts), can be saved for auditing purposes. These receipts are stored in the AS2 audit log database for the number of days indicated in the Days to Keep Audit Logs field in the Log Settings. The icon on the AS2 Log page allows you to view the saved receipts.

This is the alias that refers to the private key used to sign the message receipt. The private key is located in the Default Private Key Store. If you do not know the alias name for the private key, click the icon to select the private key alias.

If a return receipt is requested by Web User, select if the MDN will be sent automatically during the Web User's session or manually after the message is processed. The icon on the AS2 Log page indicates a manual receipt needs to be sent for a message. A manual receipt can only be sent if a message is received successfully. If an error occurs during transmission, an asynchronous receipt is sent automatically.

If enabled, the proxy server is used to send asynchronous MDN. The following proxy configuration details are enabled:

The host name or IP address of the proxy server.

The port number to use for connecting to the proxy server.

The user name to use for connecting to the proxy server.

The password to use for connecting to the proxy server.
