Selecting "Do not send delivery reports" disables the sending of read receipts for mail-enabled groups

On the Exchange Advanced tab of a mail-enabled group's properties, you have the following three options for delivery reports:

• Send delivery reports to group owner
• Send delivery reports to message originator
• Do not send delivery reports

If you select Do not send delivery reports, you also disable the sending of read receipts.

When you have the Send delivery reports to message originator setting selected on a distribution list, we are using the return path <user@domain.com>

When you have the Do not send delivery reports setting selected on a distribution list, we use the return path <>.

The reportToOriginator attribute is set to False to prevent someone from sending a message with request for delivery report to a distribution list. When the server tries to send back the delivery report to the sender, it does not send that information back. The From field is blank for two reasons:

• To prevent outside user from finding the members on a distribution list.
• To prevent a possible mail storm to that Distribution list and to its members.
