Added SMTP-AUTH / TLS now mail doesn't sign

I don't know if it's correlated at all or not, but my outgoing mail stopped
signing today. I'm now getting:

result = fail
Details: bad RSA signature

When I send a test message to Brandon Chekett's test site.

The only thing I did was add SMTP-AUTH and TLS to the mail server today, to
allow me to send signed mail from Outlook through the server. But that
shouldn't have had anything to do with the DKIM keys, right?

Just to be safe, I rebuilt the keys and re-pasted it into my DNS records,
but I'm still not validating. Here's the output:

Message contains this DKIM Signature:
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed;;
        s=default; t=1289344613;

Any ideas????
