qmail-dk (aka DomainKeys), I'm sad to say, has some bugs in the inbound
(checking) area. Someone (I'm sorry I don't remember the name) spent
some time on it a couple years ago, and ran out of time fixing the
outbound portion.
I recommend removing all DK* variables in the tcp.smtp file, except for
DKSIGN. I believe DKSIGN works ok (I have it configured), but I wouldn't
bet my life on it.
I believe DKIM is preferred (a successor to DK). I haven't used it yet,
but I believe Jake and Amit have implemented DKIM successfully. See
http://wiki.qmailtoaster.com/index.php/How_to_Setup_DKIM_with_Qmail_Toaster
I don't know how well DK and DKIM play together, but if I implemented
DKIM, I would disable DK entirely, either by removing DKSIGN in
tcp.smtp, or (better) change the /var/qmail/bin/qmail-queue symlink to
point to qmail-queue.orig instead of qmail-dk.
It appears to me that this DKIM implementation is for outbound only. I'm
not aware of any implementation of inbound checking of DK (which works
reliably) or DKIM for QMT. It'd be nice if someone would come up with a
DKIM checking patch of some sort.

Greeting QMT and QTP affectionados...
I endeavored to help PV Anthony resolve his SpamDyke issues a little bit
ago and discovered to my dismay that my DomainKeys system was rejecting
messages for no good reason -- ESPECIALLY if the sending domain had NO
DomainKeys DNS entries!
Needless to say, this is problematic, so I've temporarily suspended
checking for DomainKeys....
Has anyone else experienced this recently? (I've used DomainKeys for
quite some time without reason to suspect it was problematic! Was I just
blind to the issues all this time??)
Thanks in advance to any who choose to discuss this...
