Encrypted Mailbox - Sent folder unencrypted?
quote from the https://kb.mailbox.org/display/MBOKBEN/The+Encrypted+Mailbox :
"e-mails you compose with your mail client and save to the Sent folder are unfortunately not encrypted at the moment".
1) What do you mean by "your mail client"?
2) Is the server-side data in the "Sent objects" folder visible in the web UI always encrypted, after enabling the Encrypted Mailbox option?
