Not sure where to make bug reports which is why I asked here, but
there are a ton of bugs. Here are a few that I can recall off the top
of my head.

1) No reporting at all. Mail gets dropped without notice to the admin
2) Doesn't honor disabling. If you disable it, qmail-dk can still drop mail.
3) Doesn't honor testing flag in DNS
4) Doesn't set "h=" flag which states what is covered by the sig
(causes forwards and backup mx mail to fail)

This is just to start. I am a lead on the QmailToaster project
(http://www.qmailtoaster.com/) and qmail-dk is about to be removed
because it isn't consistent behavior. It is scheduled to be removed
from our distribution.

Assumes facts not in evidence.  How is it broken?  Do you have a bug report to
make?
