I appreciate the cheekiness of calling it the "Dark Mail Alliance", but from a purely PR perspective, it would make sense to reconsider your name if you are taking the position that encrypted end-to-end email is not solely an interest of those pursuing shady or deviant activities.
I totally agree, I really think you should change the name. Some suggestions: - Locke Mail [from John Locke] - Mill Mail [from John Stuart Mill] - Hobbes Mail - Liberty Mail
-SecMail (Secure Email)
-PrivMail (private/privacy email)
-FMail (freedom email)
-NetMail (New Internet standard email)
And thank you for taking this on, it is seriously needed. And please, no reliance on CA certs, chances are the NSA has compromised at least some of those.
