Supposedly Exim now comes stock with Yahoo's DomainKeys support (as noted at [url removed, login to view]). However, I need more concrete instructions than the general instructions provided there.
I am looking for very specific instructions to tell me how to enable DomainKeys on my particular installation, which may include upgrading my version of Exim. This will likely require some emailing back-and-forth. I am running the following on a [url removed, login to view] VPS account:
RedHat 9 i686 - WHM X v3.1.0
Exim [url removed, login to view]
Note: I'd like to submit the results of this project as a wiki entry somewhere for general use, if the notes could be of help to others.
