doom emacs mu4e error "Backend not found"

[mbenecke]

Hi,

I am not deeply into elisp, so I'm not able to solve this puzzle. I use latest doom emacs and I like the Idea to send HTML mail with org-msg

this is set in my config.el: (setq mail-user-agent 'mu4e-user-agent) ;; Use mu4e as default Emacs mail agent this works fine, as far I see

mail-user-agent is a variable defined in simple.el.gz.

Value
('mu4e-user-agent)

Original Value
message-user-agent

and this is my Issue if I try to create a new mail in mu4e:

Debugger entered--Lisp error: (error "Backend not found")
  signal(error ("Backend not found"))
  error("Backend not found")
  org-msg-mua-call(mode)
  org-msg-mode(1)
  (progn (org-msg-mode (if org-msg-mode -1 1)) (setq +mu4e-compose-org-msg-toggle-next (not +mu4e-compose-org-msg-toggle-next)))
  (if (xor toggle-p +mu4e-compose-org-msg-toggle-next) (progn (org-msg-mode (if org-msg-mode -1 1)) (setq +mu4e-compose-org-msg-toggle-next (not +mu4e-compose-org-msg-toggle-next))))
  +mu4e-compose-org-msg-handle-toggle(nil)
  +mu4e-maybe-toggle-org-msg-a(#f(advice-wrapper :before #f(compiled-function () (interactive nil) #<bytecode 0x1578e39cf8bd>) +mu4e-ensure-compose-writeable-a) 1)
  apply(+mu4e-maybe-toggle-org-msg-a #f(advice-wrapper :before #f(compiled-function () (interactive nil) #<bytecode 0x1578e39cf8bd>) +mu4e-ensure-compose-writeable-a) 1)
  mu4e-compose-new(1)
  funcall-interactively(mu4e-compose-new 1)
  call-interactively(mu4e-compose-new nil nil)
  command-execute(mu4e-compose-new)

any idea how to proceed?

configuration issue, I have no clue what in detail, total Reset of the mail config part did the job.

Now I am able to use org-msg
