Btw, I might clarify that I am just reporting what I see on my end for informational purposes and am not campaigning for anything. A DKIM pass is indicative of a legitimate message but the inverse (DKIM fail indicating illegitimacy) is not true.

Caleb's message passed DKIM (2048 bit key).
Caleb's message used utf-8 base64 encoding.
Chris' message used us-ascii 7-bit encoding. Seems like I remember 7-bit/ascii can be problematic for DKIM signatures when messages pass through multiple layers like amavis, spam assassin, postfix, etc. But I thought I remembered SPF checks in headers too so there's that. :) (It may have been spam assassin.)
