Issues with sending mail in mu4e

[jgoerzen]

What did you expect to happen?

Mail would be sent without an error and a copy stored in Sent, and it should be done in a consistent way regardless of where the point is.

What actually happened?

This may, incidentally, be a problem of documentation; none is provided on how to actually send a message. I am a long-time user of mu4e and migrating to doom. I did not previously use org-mode for composition.

I start a message. I can type it. With my point in the body area, I guess I have to type M-m C-c C-c to send it.

When I do so, I immediately get the message "Already sent message via mail; resend? (y or n)". Even on a brand-new message I just typed. If I hit y, it is sent (once) but is not saved into the Sent folder.

HOWEVER, if my cursor is up in the headers area, all I have to do to send is type C-c C-c. When I do that, I get no "Already sent" message and it is properly copied to my sent mail folder.

I am not using evil mode but otherwise am using the default keybindings with minimal on top.

Additional details:

Here are some excerpts from my config.el:

(setq +mu4e-backend 'offlineimap)
(set-email-account! "personal"
                    '(( user-mail-address      . "jgoerzen@[redacted]"  )
                      ( user-full-name         . "John Goerzen" )
                      ( mail-host-address . "complete.org" )
                      ( send-mail-function . sendmail-send-it )
                      ( mu4e-drafts-folder . "/personal/Drafts")
                      ( mu4e-sent-folder   . "/personal/Sent")
                      ( mu4e-trash-folder  . "/personal/Trash")
                      ( mu4e-refile-folder . "/personal/Archives")
                      ( mail-interactive . nil)
                      ( sendmail-program . "/usr/sbin/sendmail")
                      ( mu4e-view-auto-mark-as-read . t)
                      )
                    t)
(after! mu4e
  (load-file "~/.doom.d/config-mu4e-after.el")
)

And in the config-mu4e-after.el (which I have verified is loading):

  ; Restore some defaults that doom screws with.

            ("/other/INBOX"     . ?I)
            )
        )

In researching this, I have found multiple additional issues:

• The shortcut to attach a file is broken (C-c RET f, or M-m C-c RET f).
• Invoking mml-attach-file inserts the <#part... bit but the file is never attached; that text is simply included literally in the sent email

Further research shows that org-mu4e-compose-org-mode is deprecated by the author. There have been several attempts to do this other ways; for instance this one which was referenced in mu PR 952 although it was stated attachments are still not working right.

At this point, I believe the better user experience would be from removing the :hook (mu4e-compose-mode . org-mu4e-compose-org-mode) from the configuration.

[jgoerzen]

This is an effective workaround:

(after! mu4e
  (remove-hook 'mu4e-compose-mode-hook 'org-mu4e-compose-org-mode)

)

As of bfb0410 I've replaced the deprecated org-mu4e with org-msg. This was an overdue change. I haven't used mu4e in some time so I hope this resolves your issue. Let me know if that isn't the case and I'll reopen the issue. Thanks for bringing it to my attention!
