I would worry less about the users and more about breaking clients. The method of "be liberal about what you receive and conservative about what you send" is apt. Being standards-compliant is safe. > Those clients, and i do not even know how well GMail or Outlook > (or Apple Mail) can deal with S/MIME or PGP signed or even > encrypted (hmm..) email, would have to take and treat the secured > headers as the real ones.

Outlook and Apple Mail are able to use S/MIME out of the box. GnuPG is something you have to work on to get to a functioning state, but it is possible. For GMail there is a browser-plugin called FlowCrypt that will give you GnuPG encryption. For Apple Mail, using MacGPG will do the same. Not sure about browser mail via icloud.com, but FlowCrypt should work there too (I just have not tested it). Outlook and GnuPG I have not tried to get working, but there is some GUI offering of GnuPG for Windows, so I assume it is possible. > |I would like to hold off on this until the draft becomes an RFC, if \ > |it does. Agreed - though as Mutt can produce at least the Subject line this way when signing messages, we can test different mail clients to see how they behave. I will endeavour to test Mac Mail, Outlook (new) and web-UI for Gmail, Outlook and Apple mail to see how they render it. I will also test KMail. I do not envisage clients breaking, but never say never. Stranger things have happened throughout history. -- Kind regards, /S
