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? http://www.howtoforge.com/postfix-dkim-with-dkim-milter-centos5.1
I think the procedure might be slightly different (although I haven't tried), but nevertheless the tutorial should give you the idea.
Thank you. I ended up finding the docs here (they were installed by the RPM on my system) /usr/share/doc/packages/dkim-milter Here's another thread documenting my efforts w/openSuse 11: http://forums.opensuse.org/network-internet/389927-opensuse-mtas.html
I also had "dkim=neutral (body hash did not verify)" but it turns out to be a different issue. It turns out that whenever mail() in php is used to send emails, gmail tells me off saying hash did not verify. If I send it from command-line / shell script, it's ok. It's metioned here as well: http://allaboutlamp.com/2009/09/setup-dkim-for-postfix-in-fedora-using-dkim-milter/
