I have recently come to the conclusion that #e-mail is fundamentally unsecurable. The things we want out of e-mail, and an e-mail system, are not readily compatible with encryption. I advise people who want communications security to not use e-mail, but instead use an encrypted message client like #OTR or #Signal.
