I am using Opera Mail, with a large number of accounts (17) connected via IMAP.
In the mail panel, I see all of the inboxes, but I also have 1 mailbox with the title - All Messages. I am aware that I can remove this All Messages folder by unticking the appropiate option in the mail panel view settings, however I was hoping to see if there is a way to disable this feature completely.
Essentially, the All Messages folder shows all messages from all IMAP folders. However, this is allowing other users to view messages not intended for them. Hence my desire to Disable completely and not just remove from view.
Can this be done
