SMTP: Return Receipts Sent If "Return-Receipt-To" Is Blank
Article ID: 113824

APPLIES TO
- Microsoft Mail Gateway to SMTP 3.0
This article was previously published under Q113824
SYMPTOMS
A return receipt message is sent when the RFC 822 header "Return-Receipt-
To" field is blank.
CAUSE
The gateway knows to generate a return receipt by the presence of the field
"Return-Receipt-To" (or "Rr"). It sends the return receipt to the address
in the "Return-Path" field which it builds from the RFC 821 "MAIL From"
Address.
RESOLUTION
Configure the mail routing host so that a blank "Return-Receipt-To" header
line is not generated.
