At some point as I was going through the qmt mailing list I saw a
discussion about removing the symlink qmail-queue to qmail-dk
(domainkeys) as its deprecated and replaced by dkim.
I think you did the correct thing by unlinking qmail-dk. If you don't
use domainkeys qmail-dk is unnecessary I think.

Hi Eric/List
We're seeing a number of these errors in the smtp log. Users are also
reporting seeing some of these responses. Is there a recommended fix?
554 qmail-dk: Cannot sign message due to invalid message syntax (#5.3.0)
I came across this suggestion after Googling the error:
Disable domain keys:
rm -f /var/qmail/bin/qmail-queue
ln -s /var/qmail/bin/qmail-queue.orig /var/qmail/bin/qmail-queue
