I did several tests, all starting from emacs -Q.

First of all by default 'completion-at-point-functions is set to
(message-completion-function t). With that, TAB completes correctly
incomplete names from bbdb, case insensitive, and offers several
candidates:

with point after "fan" in the To: field, TAB completes to "fanton", and
a second TAB offers to choose between several bbdb entries with the
surname fanton.

In that case the completion is done by 'bbdb-complete-name not
'eudc-expand-inline.


With (setq eudc-server-hotlist '(("localhost" . bbdb)))

fan TAB displays "Multiple matches found: choose one", TAB then offers to
choose between all the bbdb entries with "fan" either in the name, the
email adress. This time, it's 'eudc-expand-inline doing.

The previous attempts were without corfu. With:

--8<---------------cut here---------------start------------->8---
(package-initialize)
(use-package corfu)
(global-corfu-mode)
--8<---------------cut here---------------end--------------->8---

it gets weird. Both 'eudc-expand-inline and 'bbdb-complete-name act as
they did previously but somehow TAB doesn't execute either of them, even
though it's bound to 'message-tab' (according to 'describe-key) and
'message-tab does execute 'bbdb-complete-name' or 'eudc-expand-inline'
as it should.

I checked the value of completion-at-point-functions in message-mode,
and it's set to (message-completion-function t), with no mention of
eudc-capf-message-expand-name.

Following your recipe, I tried:

--8<---------------cut here---------------start------------->8---

(add-hook 'message-mode-hook
          (lambda ()
            (setq-local completion-at-point-functions
                        (delq 'message-completion-function
                              completion-at-point-functions)
			)))
--8<---------------cut here---------------end--------------->8---


and:

--8<---------------cut here---------------start------------->8---
(add-hook 'message-mode-hook
          (lambda ()
            (setq-local completion-at-point-functions
                        (append '(eudc-capf-message-expand-name) (delq 'message-completion-function
                              completion-at-point-functions)
			))))
--8<---------------cut here---------------end--------------->8---

The first one sets completion-at-point-functions to t, and the second
one sets it to (eudc-capf-message-expand-name t). Both fail to use a
corfu completion menu when using TAB on "fan" and go back to the
dialogues previously provided if I'm using (bbdb-complete-name) or
(eudc-expand-inline).

I hope these tests are what you had in mind and can be of use to
you. Please let me know what else I can try.

Thanks for your help
