I use mh-e, but the principle should apply.  Assuming there is a hook
that gets run after rmail has read new mail (is it the "g" key?  it's
been a long time :-), you ought to be able to hang this lambda on it
and get the effect you want.  This is from my .emacs:

(setq mh-inc-folder-hook '(lambda ()
  (if (and (boundp 'display-time-process) display-time-process)
      (start-process "update-time-display" nil
		     "/bin/sh"
		     "-c" (concat "kill -14 "
				  (int-to-string
				   (process-id display-time-process)))))))

Caveat: once in a long while, your loadst process (the thing that
provides time, loadav and "[Mail]" to the modelines) may die; simply
re-run (display-time) to resume it.

Given that you have lotsa spare cycles (running on a Cray, right? :-)
you can also set display-time's update interval parameter to something
other than its default of 60 seconds.  How about 1?  Here's its defvar:

(defvar display-time-interval 60
  "*Seconds between updates of time in the mode line.")
