Aloha everyone,
Just for completeness, here's the final result, and it's much much
better. In BBDB just 'i' a 'language' field for those correspondents
with whom you correspond in whatever language, and then enter the input
mode, like 'french-postfix'. As long as you're using message mode and
BBDB completion, this works. If you use gnu-alias, initialize that
before you get to the code below, as the message-setup-hook I add
should be the last in the chain.

(defun rjn-change-lang-by-addressee ()
(interactive)
(let ((addressee (message-fetch-field "To"))
netaddr person langpref)
(if addressee
(setq netaddr (cadr (mail-extract-address-components addressee))))
(if netaddr
(setq person (car (bbdb-search (bbdb-records) :mail netaddr))))
(if person
(setq langpref (bbdb-record-field person 'language)))
(if langpref
(set-input-method langpref))))
(add-hook 'message-setup-hook 'rjn-change-lang-by-addressee t)
(advice-add 'bbdb-complete-mail :after #'rjn-change-lang-by-addressee)

This could but shouldn't be simplified with multiple let* assignments,
as nil fields cause error messages to be emitted in some of the
functions. The serial 'if' statements cause negligible additional run
time. If 'langpref' is invalid, there's a message, and that's a good
thing.
