DOCUMENT:Q113824 05-NOV-1999 [pcmail] TITLE :SMTP: Return Receipts Sent If "Return-Receipt-To" Is Blank PRODUCT :Microsoft Mail For PC Networks PROD/VER:MS-DOS:3.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Mail Gateway to SMTP, version 3.0 ------------------------------------------------------------------------------- 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.
