Install

Put mu4e-multi where you place all your Emacs Lisp files and (optionally) byte-compile it. One way to do it is to visit the file with Emacs and then issue M-x byte-compile-file

After that add the following to your .emacs:

(add-to-list 'load-path "/folder/containing/file")  ;; if it's not already in `load-path'
(require 'mu4e-multi)

Usage

mu4e-multi just depends on setting the mu4e-multi-account-alist properly and calling mu4e-multi-enable.

As an example let's assume you have two email accounts: personal and work. For handling such accounts mu4e-multi assumes your maildir's layout is as follows:

+ Maildir
+-- personal
+---- Inbox
+---- Sent
...
+-- work
+---- Inbox
+---- Sent
..

This is what you'd have in your .emacs:

(require 'mu4e-multi)

(setq mu4e-multi-account-alist
      '(("personal"
         (user-mail-address . "[email protected]")
         (mu4e-drafts-folder . "/personal/Drafts")
         (mu4e-follow-up-folder . "/personal/FollowUp")
         (mu4e-hold-folder . "/personal/Hold")
         (mu4e-refile-folder . "/personal/Archived")
         (mu4e-sent-folder . "/personal/Sent")
         (mu4e-trash-folder . "/personal/Trash"))
        ("work"
         (user-mail-address . "[email protected]")
         (mu4e-drafts-folder . "/work/Drafts")
         (mu4e-follow-up-folder . "/work/FollowUp")
         (mu4e-hold-folder . "/work/Hold")
         (mu4e-refile-folder . "/work/Archived")
         (mu4e-sent-folder . "/work/Sent")
         (mu4e-trash-folder . "/work/Trash"))))

(mu4e-multi-enable)

This alist key is the nickname of the account, which I strongly recommend that you make it match your maildir's sub-folder as in the example. For every cons in the alist, its car is the symbol of the variable to be set for this particular account and its cdr is its new value.

Calling mu4e-multi-enable makes mu4e standard folders to be aware of the multiple account configuration by setting mu4e-sent-folder, mu4e-drafts-folder, mu4e-trash-folder and mu4e-refile-folder to a callable that would properly set folders for each account, and will set a message-mode-hook to detect and set the current account variables based on the email address. If for some reason you wish to rollback these changes, just call mu4e-multi-disable.

Custom folders and markers

Notice that, in our example, the mu4e-hold-folderand mu4e-follow-up folders are not really standard ones, but since I use the GTD approach on handling emails I needed them.

Now, the thing is that mu4e obviously won't have commands to mark messages to be moved to such folders, but thanks to mu4e-multi's mu4e-multi-make-mark-for-command macro, you can generate those commands easily.

;; Creates `mu4e-multi-mark-for-hold' command.
(mu4e-multi-make-mark-for-command mu4e-hold-folder)
;; Creates `mu4e-multi-mark-for-follow-up' command.
(mu4e-multi-make-mark-for-command mu4e-follow-up-folder)

Now the only thing left is to add these new commands to the mu4e-headers-mode-map:

(define-key 'mu4e-headers-mode-map "h" 'mu4e-multi-mark-for-hold)
(define-key 'mu4e-headers-mode-map "f" 'mu4e-multi-mark-for-follow-up)

Composing

To compose a new email, mu4e-multi comes with a wrapper over mu4e-compose-new called mu4e-multi-compose-new which takes care of detecting and handling account vars properly when composing new emails.

It's strongly recommended you use this over mu4e-compose-new. This is how I bind it my local setup:

(global-set-key (kbd "C-x m") 'mu4e-multi-compose-new)

MSMTP integration

mu4e-multi comes with mu4e-multi-smtpmail-set-msmtp-account, which is a function intended to be added to the message-send-mail-hook and which will take care of appending the current account nickname to the msmtp command.

Note that for this to work properly, all your defined account sections of your .msmtprc must match your mu4e-multi-account-alist account nicknames.

If you happen to be using msmtp, enable this feature like this:

(add-hook 'message-send-mail-hook 'mu4e-multi-smtpmail-set-msmtp-account)

Requirements

Just mu4e.

NOTE: I haven't tested this in Emacs versions less than 24.x.
