Part of the point seems to be having a standardised notification system, which, if its functional, is a good idea. About a third of the way down the RFC they have a nice ASCII drawing of what happens if you have a mail system running behind a gateway and how the message notifications are handled if the necessary hosts support DSN.

This diagram indicates that if qmail supports DSN, it would support DSN at the interface between qmail and some non-smtp compliant MTA. If that's really the case, it's not a qmail issue at all. -- Raul

The right way to support this, in qmail, would be to write a small little program you can drop into your .qmail file, to report successful delivery. -- Raul

Read http://www.faqs.org/rfcs/rfc1894.html (honestly, read the first few pages at least). Basically it tries to solve issues that VERP does not. It doesn't solve the bouncing issue as well as VERP, but it tries to establish a standard way to communicate between MTAs and MUAs about whether a message has been successful and, if it was not, why and according to which MTA. > Peter van Dijk wrote: > > > On Mon, Sep 25, 2000 at 09:34:27AM +0200, Olivier M. wrote: > > > As seen on freshmeat.net this morning... > > > Any chance so see such improvments to qmail comming? > > > > No, because DSN is not an improvement.

Please explain why you feel that RFC 1894 describes an invasion of privacy (or, to be fair, a potential one). Part of 1894 is to try and track failed deliveries on mailing lists (in a less efficient way than Dan's solution, mind you). A major part of the goals of 1894 from my reading of it is to allow the reporting of potential error conditions from different mailing infrastructures operating on the other side of SMTP gateways (which there are a lot of).
