Old question, but since it is the first thing that pops up in google (at least for me), I guess it is worth updating.

The answer provided by @miguelmorin no longer works (see C.4.9 in https://www.djcbsoftware.nl/code/mu/mu4e/Writing-messages.html). You now have to use mu to register your email address (with mu init --maildir=/path/to/mail/folder [email protected]). After this, you can control de inclusion of your email address in CC while a reply-to-all configuring the mu4e-compose-keep-self-cc in emacs (it defaults to nil).

The answer provided by @miguelmorin no longer works, see the manual for Writing messages, C.4.9:

You need list your personal addresses by passing one or more --my-address=... to mu init. Note that the mu4e-user-mail-address-list which was used in older mu4e versions is no longer used. Also see the entries for version 1.4 in NEWS.org (N) in the main-menu.

You now have to use mu to register your email address:

mu init --maildir=/path/to/mail/folder [email protected]

After this, you can control the inclusion of your email address in CC while a reply-to-all configuring the mu4e-compose-keep-self-cc in ~/.emacs (it defaults to nil).

If you have multiple email addresses, you need to include that many --my-address=... parameters, per the documentation:

mu init --maildir=~/Maildir [email protected] [email protected]
