You can always drop in your own routers/transport without having to
interfere with the debconf-driven mechanisms.

References to /usr/shade/doc/exim4-base/README.Debian are all over the
place. We have even changed spec.txt to refer there.

What's your proposed solution to the problem? If you bitch, you'd
better have a clue about how to do things better.

You're free to do that decision. But, please, don't discourage newbies
from using the things that we came up with. There is actual brain work
inside there.

Which parts of our configuration can be performance impacting? And how
many of them might impact performance so that it becomes relevant for
an end-user desktop system?

Actually, you should say "next to never".

Actually, in the last weeks before release, the release team was
pretty cooperative. The reason I pushed for 4.50 in sarge was
exiscan's integration in the upstream source because the Debian build
process could be greatly simplified by removing the need to patch the
upstream sources before daemon-heavy build.

Please compare how many bugs I fix while I am saying "send a patch"
once. Then reverse the ratio, and find the ratio valid for M'd.

I disagree here. We have a fair share of users on dialup, and using
ssmtp on a dialup line _WILL_ lose mail since ssmtp doesn't queue at
all. ssmtp is fine for a host which has a 24/7 smarthost cluster with
five nines of availability on the local LAN, but a queueing MTA is
necessary for the default install.

The majority of dumb newbie questions come from people who don't have
a clue about e-mail but want to run a publicly available, multi-user,
probably commercial server on the Internet with even more features
than the feature set that we offer with the default install.

That's not a problem. Debian has committed itself to keep the exim in
a stable release useable, as we did with exim 3, and still do. The
same will go for exim 4. Additionally, Andreas is already offering
"official" sarge backports of later exim4 packages. These are
prominently linked from the Debian exim4 web page.

Debian has always been a distribution for people wanting stability,
and has always not catered well for version number junkies. That's a
feature, and not a problem.
