Never mind. After digging a bit around in the code i came up with
following approach ....

	(add-hook
	 'bbdb-complete-name-hooks
	      '((lambda ()
		  (if (mew-draft-or-header-p) 
		      (let* ((rec (if (boundp 'match-recs) (car match-recs) rec))
			     (keywords (if rec (cdr (assoc 'keyword (bbdb-record-raw-notes rec))) ""))
			     (email    (if (boundp 'this-addr) this-addr "")))
			;(message (concat "k:" keywords " e:" email))
			(cond
			  ; ....
			  ; rules which set case based on email and keywords ...
			  ; ....

... it is a bit kludgy as it relies on undocumented parameters in
bbdb-complete-name-hooks and to set the case i also had to unelegantly
define ...

	(defun mew-draft-set-case-non-interactive (new-case)
	  (let ((old-case (mew-tinfo-get-case)))
	    (mew-tinfo-set-case new-case)
	    (mew-tinfo-set-use-flowed (mew-use-format-flowed new-case))
	    (mew-draft-mode-name (mew-tinfo-get-hdr-file))
	    (mew-draft-replace-fields old-case)
	    (mew-highlight-header)
	    (unless (mew-tinfo-get-hdr-file) (mew-draft-header-keymap))))

... which is non-interactive version of mew-draft-set-case as i
couldn't find an existing clean function to call for setting the case
non-interactively.

So more or less i'm happy for now but any hints for more elegant
approaches are still welcome :-)
