Webmail access proposition

[illambias]

Using webpg (https://webpg.org/?view=home) you could provide a webmail sending encrypted content.
That way no more problems with html5 local storage. Providing solid ssl access you have a relatively solid solution. The webmail does not implement pgp wich allows a bigger choice and diminishes security issues.

Plus it forces the user to check his mails from a secured platform, pushing good practices.
