SUMMARY

Basic delivery status notifications can be enabled for MailEnable. This article describes how to enable this for your services.

DETAIL

To enable delivery status notifications in MailEnable, add the following registry key. The mail services need to be restarted after this change. When delivery status notifications are enabled, the sender, if it requests it using the NOTIFY option, will receive a confirmation email when the message is delivered to a users mailbox. Support for delivery notifications are limited to just this response for the NOTIFY parameter described in RFC 3461.
