 * 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.

Additional query words: 3.00 smtp return receipt
