;; Functions for storing and following links to email messages in
;; org-mode. There should be no need to call the functions in this
;; file directly; `org-store-link' should pick up the correct link
;; when invoked from a message or mailbox buffer, and
;; `org-open-at-point' should handle BIC links.
