There are lots of threads on DKIM Failure and I have been reading through them. I don't seem to see anything too current, so please forgive me if I missed the one that would have answered my question.
Is there any update on when the DKIM Failure issue will be resolved. Most threads point to an Exim issue.
I installed domain name keys and everything works except when testing the return is: DKIM-Status: failed (no signature found)
