- Return-Receipt-To is a kluge and a hack invented and first used by the
- abominable sendmail program for BSD Unix. It is not standardized,
- neither as a header, nor as functionality. No one has bothered to write
- up a specification for it and submitted it as an RFC. It's generally
- considered a Bad Thing because (1) not all mailers implement it, so
- absence of a returned receipt means nothing, and mail is not 100%
- reliable, anyway, so even if a receipt is generated, it may not get back
- to you, especially if headers get rewritten and the address in the
- header is useless where generated, (2) it's often used indiscriminately
- by those who use it all, causing much wasted bandwidth, and (3) it gives
- users the impression that they can get a service that doesn't exist in
- the Internet mail system.
-
- 'Tis best to ignore it entirely.
-
- An argument could be put forth that it should be deleted, but this
- requires some level of recognition of it, which is almost as bad as
- responding positively to it.
-
- Let's hope that 1993 will see a replacement for sendmail, and wide
- deployment of real MTA software, to support 8-bit data paths, MIME, etc.
- I might as well hope for the demise of X.400 while I'm at it.
