You would probably need `search-forward-regexp' and
`match-string'. The code below will not work but it will give you an
idea on how to do it:

(defun blah ()
 (let (adresses)
  (while (search-forward-regexp "\\(REGEXP-MATCHING-EMAILS\\)" nil t)
   (setq addresses (append adresses (list (match-string 1)))))
  adresses)

Matching e-mail addresses using a regexp can be tricky, if you want to
support all variants (with `+' before the @ and such).

This sort of works interactively, that is it finds most of them. Blah is
missing a final parenthesis and I don't understand if addresses with 2 d's
is outside the scope of the let or not. Anyway, it just returns a list of
nils even if some email addresses are below the point of invocation in
*scratch.

\b[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]\{2,4\}\b

Maybe all of the backslashes have to be doubled.

Yes, there were typos in the code. There should be only one variable,
`addresses'.

If they are in a string, yes.

Hi,

i would try to use somthing like

  bbdb/gnus-show-all-recipients
    Command: Show all recipients of this message. Counterpart to
             `bbdb/vm-show-sender'.

  bbdb/vm-show-all-recipients
    Command: Show all recipients of this message. Counterpart to
             `bbdb/vm-show-sender'.

Martin
