In fact you can't use gpg in mailbox.org when you send an email. Gpg is only used to encrypt your mailbox (it encrypts the emails you receive) which is kind of weird. You can of course use GPG in command line or with an external program.
Yes, we HAD access to the plaintext e-mail. And we explain that and warn about that.
But after encrypting the e-mail, nobody will have access to that e-mail any more: Even hackers, phishers or the government. Many people are storing their e-mails for years in their INBOX. Great to protect those e-mails over the time.
But, anyway: The best way is always to use real end-to-end-encryption. In that case, you don't have to trust us any more. We're happy to help to set this up.
