| automatically find the email address, though.  (On all the machines
| I currently have an account on, emacs guesses something like
| "ceder@sparky.signum.se", but the correct address is
| "ceder@signum.se"; dropping the first part of (system-name) should
| produce valid email addresses for me, but would probably break
| things for many others).

One alternate algorithm is:

   find MX-record for host A
   do {
      chop off leftmost component
   } while MX is the same

I know that this will guess wrong in a number of cases. One example is
foobar@gazonk.oslo.sgi.com which will become foobar@sgi.com rather
than the correct foobar@oslo.sgi.com. Perhaps the algorithm should
restrict itself to chop off just one level, then this class of
addresses will work, too. In any case, I think this method will be
correct in more situations.

(I don't know how to do DNS queries in elisp, perhaps the
functionality isn't there, making this moot.)
