I'm setting up my own email server. Clients will connect to this server using IMAP.
Nowadays it's possible to map the correct 'special' folders on the server to the local client (like Drafts, Junk, and Sent). However, because the majority of the devices connecting to my server will use Mail.app (or Mail on iOS), it'd be nice if the default folder names on the server correspond to the names Mail.app uses (so I don't have to remap the folders on all devices).
Therefore, my question is: what are the special folders names Mail.app uses by default?
