The domainkeys code in QMT is known to be a bit buggy, but that has only been on checking, not signing ttbomk. Is there something perhaps in the content of your test that is triggering a malfunction? IOW, how simple is the content in your test message? If it's trivial text, then I'd suspect that your configuration has an issue. Perhaps your pub/private keys got mixed up somehow?

You might want to generate a new key pair and reinstall them to be sure. Or, I believe there's a way to validate that the keys you're using belong together. I'm not that familiar with openssl off hand to tell you how to do that.

I just ran these again today and they failed on Domainkeys test. I set this
up about a month ago so DNS should have updated already.

I used sa-t...@sendmail.net with the following results:

Authentication System:       DomainKeys Identified Mail

And I also used email-t...@qmailtoaster.com with the results:

Here are the spamassassin headers from this server:

No, score=0.6 required=5.0 tests=AWL,DK_POLICY_SIGNALL,
DK_SIGNED,HTML_MESSAGE,RDNS_NONE autolearn=no version=3.2.5

Return path was: "John Raley" <j...@fmcfinance.net>

Original test request was sent using:
SPF Record:     PASS

Sent from a valid domain:     PASS

DomainKey:      FAIL

Odd. In that case, what services did you test with that did not work?
And when did you enable Domainkeys? Is it possible that your updated
DNS information had not yet spread and that those services were using
cached (and therefor wrong) DNS information. E.g. they might not have
been able to see the selector or policy record...
