Delivery confirmation is generated by the router when posting the mail in the recipient’s mailbox and is sent back to the Object Client. In SapOffice, you will see that the mail has arrived by choosing the Goto -- Transmission info option. The status of your mail will display as changed from "Message passed" to "Arrived".
When the Notes user reads the mail, the Notes mailer generates a return receipt in the Object Client.
In order for return receipt to function correctly, the original mail must address the Domino user with the same name that the return receipt will be coming from when the Domino user opens the mail. Generally, that name will be CN=User_Name/OU=OurTeam/O=OurCompany@Domain. If you access Domino address information using LDAP, the address will be in exactly this format.
Note In SapOffice 3.1x, you cannot set the flags for delivery confirmation and return receipt. When you create a new message, they are both set automatically. When you create a reply, neither flag is set. To also receive a delivery confirmation or return receipt for your e-mail reply, set the Domino server environment variable $ObjServerMinConfirmation using one of the following values.
As with all Object Server notes.ini variables, add an instance number identifier (for example, $ObjServerAddressIsInternet1, $ObjServerAddressIsInternet2) if you are running more than one Object Server process on a given Domino server. If you are running more than one instance but do not have an instance identifier, the same variable is used for all instances.
