XFOR: Internet Mail Service Is Not Copying Administrator on NDRs

SYMPTOMS

When you send a message through the Internet Mail Service, with a bad SMTP address, the receiving host may respond with a "550"' error after the RCPT TO: command is sent (RFC-821). The Internet Mail Service then generates a non-delivery report (NDR) and sends it to the user. This NDR is not copied to the Administrator mailbox, even though the notifications button on the Internet Mail Service is set to "All."

Examples of NDRs that do make it to the Administrator mailbox include the following:

• Unbalanced open & closed brackets
• Host unknown
• Max time for delivery expired
