My email configration. Currently I use [[https://github.com/gauteh/lieer][lieer]] to fetch emails from Gmail, [[http://davmail.sourceforge.net/][davmail]] & [[http://www.offlineimap.org/][offlineimap]] to fetch emails from MS Exchange, [[https://notmuchmail.org/][notmuch]] to index, [[https://marlam.de/msmtp/][msmtp]] to send emails. Also using notmuch frontend from Emacs.

My problem with any particular mail setup was that I use Gmail labels quite extensively, and handling these over IMAP is rather awkward. Notmuch seems to be the only software that provides the same first-class support for labels.

But I also have an Exchange account, with which I communicate via IMAP/SMTP adapter, and in this case, I synchronize notmuch tags and IMAP folders.

References:
- [[https://sqrtminusone.xyz/posts/2021-02-27-gmail/][My post]] about email configuration. I wrote it some time ago, but the general idea remains.

* Lieer
| Arch dependency |
|-----------------|
| lieer-git       |

Lieer is a program to link up Gmail and notmuch. Basically, it downloads mail from Gmail via API, stores them in Maildir, and synchronizes labels with notmuch.

I have a separate directory in my =~/Mail= for each address. To init lieer, run the following command in the directory:
#+begin_example
gmi init <address>
#+end_example

After which the settings will be stored in =gmailieer.json= and the credentials in =.credentials.gmailieer.json=. The latter file is stored encrypted.

My preferred settings:
#+begin_example
gmi set --replace-slash-with-dot
gmi set --ignore-tags-local new
#+end_example

Running =gmi sync= in the required directory performs the synchronization. The first sync takes a while, the subsequent syncs are pretty fast.
* DavMail
[[davmail.sourceforge.net][DavMail]] is a gateway between MS Exchange and the rest of the world, which uses IMAP/SMTP/LDAP/etc. As I have one corporate MS Exchange address, this is just the program I need.

Edit [2025-11-11 Tue]: We've moved from MS Exhange, disabling this.

It has a GUI mode, but I prefer headless config.

* OfflineIMAP
| Arch dependency |
|-----------------|
| offlineimap     |

[[https://github.com/OfflineIMAP/offlineimap][OfflineIMAP]] is a program that can synchronize IMAP mailbox and Maildir. Lieer does everything by itself, but my pirate Exchange IMAP needs this program. There is also [[https://isync.sourceforge.io/][isync]], but there I had some weird issues with duplicate UIDs, which don't occur for OfflineIMAP.

I have a few options for setting a username and password. First, I can run =pass= in =remotepasswordeval=, and while this will work, it will keep my keyring unlocked because I want to run =offlineimap= every couple of minutes.

Another option is to use noweb and not push the file below to the version control. Then I have a plaintext password of email on my computer, but I think it's a lesser evil than the entire keyring.

I would use =password-store-get= from password-store.el, but I want this to be able to run without any 3rd party packages, so it's just bash.

* Notmuch
| Arch dependency |
|-----------------|
| notmuch         |
| parallel        |

Notmuch is an email indexer program, which handles labels in a way somewhat similar to Gmail. It also provides a frontend for Emacs, but it's not the only one available.

** Config
:PROPERTIES:
:header-args+: :tangle ~/.notmuch-config
:END:

Not much is going on here.

First, the database path. It's different on desktop and termux.
#+NAME: get-maildir-path

(expand-file-name "~/Mail")
#+end_src

#+begin_src conf-unix :noweb yes
[database]

#+end_src

My name and list of emails. It's not like it's a secret anyhow.
#+begin_src conf-unix
[user]

primary_email=thexcloud@gmail.com
other_email=progin6304@gmail.com;pvkorytov@etu.ru
#+end_src

#+begin_src conf-unix

#+end_src

Maildir compatibility.
#+begin_src conf-unix
[maildir]
synchronize_flags=true
#+end_src

** Hooks
Now we have to link up lieer & davmail's maildir and with notmuch. This is done via the notmuch hook system, which allows running custom scripts before and after any command.

With lieer and Gmail, it is enough to simply run the program, because Gmail has first-class support for tags. Maildir does not, so I decide to synchronize notmuch tags and IMAP folders. In essence, the idea is to:
- move emails to their folders by tags /before/ the synchronization
- tag mails by their folders /after/ the synchronization

The problem is that with that approach one email can have only one tag, but it's better than nothing.

So, here are the rules which match tags & folders:
#+NAME: pvkorytov_tags
| tag                      | folder                   |
|--------------------------+--------------------------|

| sent                     | Sent                     |
| spam                     | Junk                     |
| trash                    | Trash                    |
| job.digital              | Job_Digital              |
| job.digital.docs         | Job_Digital.Docs         |

| etu.grad-school          | Etu.Grad_School          |

&BCMENAQwBDsENQQ9BD0ESwQ1-

And below is a noweb function, which generates the following commands for notmuch to execute:
- /before/ sync:
  - =notmuch search --output files "NOT path:[PATH] AND tag:[TAG] AND tag:[ROOT_TAG]" | xargs -I ! mv ! [PATH]=
    Move emails with =TAG= but outside the matching =PATH= to the latter
  - =notmuch search --output=files "NOT path:[ARCHIVE_PATH] AND tag:[ROOT_TAG] AND NOT tag:[TAG1] ... AND NOT tag:[TAGN]" | xargs -I ! mv ! [ARCHIVE_PATH]=
    Move untagged emails to the =ARCHIVE_PATH=
- /after/ sync:
  - =notmuch tag +[TAG] "path:[PATH] AND NOT tag:[TAG]"=
    Tag emails in =PATH= which do not yet have the matching =TAG=
  - =notmuch tag -[TAG] "NOT path:[PATH] AND tag:[TAG] AND tag:[ROOT_TAG]"=
    Remove =TAG= from emails which are outside the matching =PATH=

These rules are getting included in the respective hooks.

*** =pre_new=
This hook runs fetch from Gmail & offlineimap in parallel before the =notmuch new= command. The =parallel= command is provided by [[https://www.gnu.org/software/parallel/][GNU Parallel]].

It isn't necessary to run =cd= for offlineimap, but it's easier to write that way.

Sending emails can be done with MSMTP. It automatially chooses the email address and server based on the contents of the message, which is handy if there are multiple mailboxes to be managed.

* Emacs

| notmuch    |

Finally, Emacs configuration. Let's start with some variables:
#+begin_src emacs-lisp
(setq user-mail-address "thexcloud@gmail.com")
(setq user-full-name "Pavel Korytov")
#+end_src

TODO fix for Arch

Then, the problem with my Guix setup is that Emacs by default doesn't see the elisp files of notmuch, so here is a small workaround:
#+begin_src emacs-lisp
(let ((dir  "/home/pavel/.guix-extra-profiles/mail/mail/share/emacs/site-lisp"))
  (when (file-directory-p dir)
    (let ((default-directory dir))
      (normal-top-level-add-subdirs-to-load-path))))
#+end_src

On termux the above doesn't work, and I don't need it here anyway.

Some functions to toggle tags:
#+begin_src emacs-lisp
(defun my/notmuch-toggle-trash ()
  (interactive)
  (evil-collection-notmuch-toggle-tag "trash" "search" #'ignore))

(defun my/notmuch-toggle-inbox ()

(defun my/notmuch-toggle-unread ()
  (interactive)
  (evil-collection-notmuch-toggle-tag "unread" "search" #'ignore))
#+end_src

And notmuch settings:
#+begin_src emacs-lisp
(use-package notmuch
  :commands (notmuch notmuch-search)
  :init
  (my/use-colors
   (notmuch-wash-cited-text :foreground (doom-color 'yellow)))

#+end_src
** Tuning signature
Edit <2024-08-19 Mon>: Apparently this was a feature, not a bug. Disabling this.

By default, =message.el= inserts the signature at the bottom of the message, like this:

#+begin_example
<message text>

Person <person@mail.org> writes:

> Stuff

--
Yours,
me
#+end_example

This creates issues with certain email clients. For instance, MS Exchange often just cuts the text at =Person <person@mail.org>....=, so there's no way to see the signature from the UI.

What's more, MS Exchange, Gmail and other such clients add the signature before the quotation block, like that:

#+begin_example
<message text>

#+end_example

So here I modifiy the citation function to insert the signature like in the second example for +certain cases+.

Edit <2022-10-27 Thu>: for consistency's sake, I'll make the signature on the top for all cases.

Edit <2024-08-19 Mon>: see above

#+begin_src emacs-lisp
(defun my/message-insert-signature-need-on-top ()
  t)
#+end_src

Then advice the =notmuch-mua-reply= function:
#+begin_src emacs-lisp
(defun my/message-maybe-fix-signature (&rest _)
  (when (my/message-insert-signature-need-on-top)
    (save-excursion
      (goto-char (point-min))
      (when (re-search-forward message-signature-separator nil t)
        (move-beginning-of-line 0)
        (kill-region (point) (point-max)))
      (message-goto-body)
      (when (re-search-forward (rx "sign=pgpmime") nil t)
        (forward-line))
      (insert (current-kill 0))
      (insert "\n\n")
      (set-buffer-modified-p nil))))
