I am using qmail and libdkimtest to sign outgoing emails. The setup is almost exactly as per this tutorial (

Emails I send out have a signature added, and it looks fine to me however, spamassassin reports:

    *  0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily
    *      valid
    *  0.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid

I've added the DNS records exactly as many tutorials suggest. I've tested the DNS with and it doesn't report any problems, and displays the public key correctly.

I would like to get more detailed errors in order to figure out why spamassassin says it isn't valid.
