A global minor mode that defines a full working setup for mu4e and mbsync, based on mu 1.8+. Easily setup accounts and aliases from these providers: Google, Apple, GMX and Proton. Additional packages are installed and configured for a better experience, including mu4e-column-faces, mu4e-alert, org-msg and helm-mu. Some customizations are available, run (customize-group 'mu4easy).
Install locally and use the load-path variable, e.g.:
(use-package mu4easy
:load-path "~/Code/mu4easy"
:bind ("C-c u" . mu4e)
:config (mu4easy-mode))Or install with Melpa. Here is an example with one email account:
(use-package mu4easy
:ensure t
:bind ("C-c u" . mu4e)
:config (mu4easy-mode)
:custom
(mu4easy-contexts '((mu4easy-context
:c-name "Google"
:maildir "Gmail"
:mail "[email protected]"
:smtp "smtp.gmail.com"
:sent-action delete))))See later more details on the mu4easy-context macro.
Make sure you have mu in your in PATH.

The important part is to normalize all accounts to have the same structure, containing the folders Inbox, Archive, Sent,
Trash, Drafts and Spam. I would advice against syncing the Drafts folder because it can lead to issues. If you decide
not to sync it, just remove the relevant lines from the .mbsyncrc file.
Let’s go over each provider and examine the gotchas.

First is the PassCmd. I assume all passwords (and application specific passwords) are in ~/.authinfo.gpg with the
password key-value pair last (see the NF variable in awk pointing to the last column).
Next, Google has the structure [Gmail]/... so we use explicit far/near definitions. We’ll drop them in the next
providers.
Finally, unlike other providers, we’re not going to sync the Sent folders because Google is saving all email in the All Mails folders and you’ll end up with duplicates locally.

In order to us Proton, one needs to install a bridge application. It specifies the IMAP and SMTP ports to use (non-standard).
Let’s go over the important parts of the elisp code.
(setf (alist-get 'trash mu4e-marks)
'(:char ("d" . "▼")
:prompt "dtrash"
:dyn-target (lambda (target msg) (mu4e-get-trash-folder msg))
;; Here's the main difference to the regular trash mark, no +T
;; before -N so the message is not marked as IMAP-deleted:
:action (lambda (docid msg target)
(mu4e--server-move docid (mu4e--mark-check-target target) "+S-u-N"))))I picked this code and realized that, at least for Google, if you flag a message trashed, it just disappears. This code
instead flags the message as seen, removes the flags unseen and new and finally, moves it to the Trash folder, which is
synced to the server and gets deleted according to a policy you control.
(cl-defmacro mu4easy-context (&key c-name maildir mail smtp

(sent-action 'sent)

(let

(,trash . ?t)
(,refile . ?a)
(,draft . ?d)))))))That’s the macro to create contexts or identities. It’s assuming you have a consistent maildirs structure, like
specified in the mbsync config, i.e. all account names are on a single level and then below them you have Inbox,
Archive, Trash, Sent, Spam and Drafts for each one. To match the context I’m just looking at the maildir the message is
in. Some defaults in the function are the SMTP encryption and what to do with sent messages (either delete them in the
case of Google or save them in the Sent folder; more on that in the contexts examples).
Next there are some variables settings; these are set to taste, feel free to experiment with them. Next are the bookmarks, which are very convenient both for jumping and for reading the read/unread counts.
Tip: the bookmarks query can be either a function or a string. If it’s a function, there is no read/unread count. I’m using a string generated from a function; if you first eval the string and then set the variable, you do get counts.
For org-msg package users, notice that the package itself handles the signature, so you want to define org-msg-signature
like I did in the macro. It accepts org formatting, e.g. *Daniel Fleischer*\n/Skynet Inc/ and then converts it into
formatted HTML. Also, when using org-msg, reply style is top-posting so you need it to handle the signature correctly
(above the replied text).
Another improvement is creating a customized link description; i.e. calling org-store-link to save a link to an email,
it uses mu4easy-mail-link-description which will give a nice description of the form to/from: subject (ISO timestamp) - works
with org-capture as well.
Added is a custom updating function that asks you which account to update, or by default updates all. It is bound to the usual “U”.
Finally, setting up the accounts, either using customization or using code:
(setq mu4easy-contexts
'((mu4easy-context
:c-name "Google"
:maildir "Gmail"
:mail "[email protected]"
:smtp "smtp.gmail.com"
:sent-action delete)
(mu4easy-context
:c-name "1-GMX"
:maildir "GMX"
:mail "[email protected]"
:smtp "mail.gmx.com")
(mu4easy-context
:c-name "2-GMX-alias"
:maildir "GMX"
:mail "[email protected]"
:smtp "mail.gmx.com"
:smtp-mail "[email protected]")
(mu4easy-context
:c-name "Apple"
:maildir "Apple"
:mail "[email protected]"
:smtp "smtp.mail.me.com")
(mu4easy-context
:c-name "3-Apple-alias"
:maildir "Apple"
:mail "[email protected]"
:smtp "smtp.mail.me.com"
:smtp-mail "[email protected]")
(mu4easy-context
:c-name "Proton"
:maildir "Proton"
:mail "[email protected]"
:smtp "127.0.0.1"
:smtp-type ssl
:smtp-port 999)
(mu4easy-context
:c-name "4-Proton-alias"
:maildir "Proton"
:mail "[email protected]"
:smtp "127.0.0.1"
:smtp-mail "[email protected]"
:smtp-type ssl
:smtp-port 999)))Important points:
- Jumping to contexts is based on their first (unique) letter, that’s why I’m using numbers in the
c-namekey. - Google saves the sent messages in the All Mail (Archive) folder so it is recommended to set the corresponding mu4e setting to delete sent messages (locally). It’s only for Google; for the other account, sent messages are saved in the Sent folder.
- The
2-GMXaccount is an alias - not another GMX account (see the last comment). It has a different mail, but the SMTP authentication needs the real email address. The outgoing email still looks like it is coming from the alias. - Proton account needs SSL encryption for SMTP, it connects to
localhostand uses non-standard ports for IMAP and SMTP (check the Proton bridge app for details). - If you have multiple accounts with the same providers, they should have different maildirs, e.g.
~/Mail/Gmail1/,~/Mail/Gmail2/. Here I showed aliases, not multiple accounts.
This setup is based upon a couple of weeks worth of tweaking, trial and error. It’s not perfect; some email were lost
(those not saved into sent), lessons were learned. I didn’t try it with Microsoft-based emails. Make sure to test
everything you do - to see that emails are going in and out, saved in Archive and Sent, compare the results with the
web-based interface until you get comfortable using it 100% of the time. Or not.
