Same here, but, if you use it with Gmail, let me recommend Abdó Roig-Maranges' fork of offlineimap, which implements labels[1][2]! That way you can sync only [Gmail].All Mail and all the other info (such as /Inbox, /Sent and any other custom labels) come as X-Keywords in the header (no duplicates, and no lost metadata)[3]. And mu4e supports all this[4]! [1] https://github.com/aroig/offlineimap https://github.com/aroig/offlineimap [2] The homebrew tap, if that's your thing: https://github.com/jeastman/homebrew-offlineimapwithlabels https://github.com/jeastman/homebrew-offlineimapwithlabels [3] [Gmail].Trash and [Gmail].Drafts are also real folders, not just labels. You should sync them too. [Gmail].Sent Mail is just a saved search for /Sent labels. mu4e asks for a "sent" folder but, since you should (setq mu4e-sent-messages-behavior 'delete) anyway with Gmail, it becomes a dummy folder locally, and all is well.
