Ease up everyone... Tasos isn't a flame-baiting troller... he probably really needs
DSN (I feel your pain Tasos, I need it too).
Anyway, he's also the author of Listproc (yeah!), which I'm still using to this day
because everything else (read majordomo) I've tried sucks hard; anyway, he's cool.

ps. here's a good reason for DSN: SMTP<->X.400 gateways. X.400 supports all kinds of
return receipts, and right now, DSN is the way our X.400 MTA provider interfaces this
stuff. I've got a sendmail box that I have to keep using because we need to be able
to turn on DSN when we send messages into X.400.
However, DSN is also a major cause of headaches for us, either Micros~1 Exchange MTA's
saying that they support it, but they really don't, to someone else's home-grown bad
implementation, to firewall smtp filters rejecting it, etc.

Why? Why not just contract with one of the commercial support
organizations (http://www.qmail.org/top.html#paidsup) that specialize
in qmail ? Even taking the cost of that into account, qmail is still
going to be cheaper to support.

This is completely unfair. The RFC for bounces is not widely
supported. Calling qmail "non-conforming" because it has its own
bounce format is like calling Eric Allman "non-conforming" just
because he's gay. Many other Open Source authors are fags (if you're
homophobic, stay clear of free software), and many other MTAs do not
support DSNs.
Dan is completely within reason to not support DSNs. As Phil Karn
once said, "A author of quality software has a duty not to support
brain-damaged standards". He was talking about IEEE 802.3 at the
time, but the principle holds true.

I see no evidence for this. Exim is Yet Another Monolithic MTA.
After working with qmail for a number of years, I can see many good
reasons for keeping your MTA small, and relying on external packages
for optional features. Basically, my feeling is that qmail is the
only genuine Unix MTA.

How deep are your pockets? I'm not saving this part of the world from
itself (I have my eye on saving a different part), so I don't share
Dan's opinion of DSNs. If you want me to implement them, just send me
a proposal and I'll quote you a price for it.
