|
;; Multiple identity support for MH-E.
|
|
|
|
;; Used to easily set different fields such as From and Organization,
|
|
;; as well as different signature files.
|
|
|
|
;; Customize the variable `mh-identity-list' and see the Identity menu
|
|
;; in MH-Letter mode. The command `mh-insert-identity' can be used
|
|
;; to manually insert an identity.
