DKIM Bad RSA Signature
by jkaidor from LinuxQuestions.org on (#6K6E1)
I just installed opendkim on my Slackware box running sendmail. I created the public and private keys, started the opendkim process, and
put the public key in my DNS, and added the filter line in my sendmail.mc. Testing it with dkimvalidator.com, I see that a DKIM header is created; but it has a bad RSA signature.
I'm at a loss as to how to troubleshoot this; the very nature of cryptographic hashes dictates that there's no such thing as "almost working". Either everything is right, or it isn't. If it isn't then the hash will be totally different.
All I can guess is that there's some kind of rewriting happening after the DKIM signature is created. Can anybody supply a clue? Maybe some common sendmail option?
