It's currently possible to delete mails (*not* move to Trash) from any
folder. What a delete action does depends on the mail client, and it is
often synonymous to "Move to trash", and aerc's behaviour can surprise
users (who will find out too late, when their mail is gone forever...).
This patch adds a configuration setting to control whether deletes are
allowed from any folder, or are restricted to the Trash and Junk
folders.
