Do you think of this?
#+begin_src emacs-lisp
(cond
((and (string= (getenv "USER") "johndoe")
(string= (getenv "HOSTNAME") "bar"))
(setq user-mail-address "johndow@bar.com")
(require 'john))
((and (string= (getenv "USER") "janedoe")
(string= (getenv "HOSTNAME") "bar"))
(setq user-mail-address "johndow@bar.com")
(require 'jane))
(t
(setq user-mail-address (concat (getenv "USER") "@" (getenv "HOSTNAME")))))
#+end_src emacs-lisp
But note that $HOSTNAME is often not set. You can use `system-name'
here.
