Perhaps the following code snippets could help (it's about using "roles"
and cycling signatures):

(defvar pm/role-history nil
  "History list for roles.")

(defvar pm/role         "private")

(defun pm/addr->role (address)
  (cl-loop for item in pm/roles
           when (string-equal (plist-get item :address) address)
           return (plist-get item :id)))

(defun pm/role->addr (role)
  (cl-loop for item in pm/roles
           when (string-equal (plist-get item :id) role)
           return (plist-get item :address)))

(defun pm/update-role ()
  "Check current buffer and update pm/role accordingly."
  (let* ((address (mail-strip-quoted-names
                   (message-fetch-field "From")))
         (role (pm/addr->role address)))
    (when role (setq pm/role role))))

               (pm/address "           ")
               "           " (pm/phone)))
     (setq pm/sig-level 0)
(defun pm/cycle-sigs ()
    (when (message-goto-signature)
      (forward-line -1)
      (delete-region (1- (point)) (point-max)))
    (incf pm/sig-level)
