DKIM & DomainKeys with Sendmail/Postfix:

    I installed and configured DKIM and DomainKeys milters for Sendmail by following the instructions from the following pages:

    http://www.elandsys.com/resources/sendmail/domainkeys.html
    http://www.elandsys.com/resources/sendmail/dkim.html

    The good thing is that I got these milters to sign all outgoing emails. However, the problem is that the signatures fail consistently for emails with a message larger than a certain size. For example, gmail says: dkim=neutral (body hash did not verify)

    For emails with a couple of sentences, the signatures always work as expected. I suspect that Sendmail is modifying the message in some manner after the email's been signed.

    I have Sendmail version 8.13.8 running on CentOS 5. I even tried using Postfix but with the same results.

    I would really appreciate some help here. Please let me know if I need to provide further information about my setup.

    Thank you very much!

    openSuse 11.0, dkim-milter rpm

    I installed the dkim-milter from the rpm that is offered by openSuse on my openSuse 11 system.

    However I could not locate any documentation/manuals so I don't know how far I'm supposed to take the installation to complete it.

    I have looked at this HowTo for CentOS on HowtoForge.

    Can someone tell me if these same steps also apply to openSuse 11 from the step after installing the rpm?

    I think the procedure might be slightly different (although I haven't tried), but nevertheless the tutorial should give you the idea.
