Comment 69 for bug 233901

I just realised that an arbitariliy named file put on
/usr/lib/mozilla-1.2.1/defaults/pref will be read, too. That's for
mozilla-1.2.1, Red Hat release. If this is standard behaviour, it ought to be
documented.

Also, I'm trying to include default mail account settings in my site config, but
can't figure out how. The problem is setting
   mail.server.<server name>.userName
This is of course user specific, but the value is always identical to the
Unix/Linux login name, so it ought to be possible to set up the value in all.js
or similar. Oh, and
   mail.identity.<id>.useremail
is needed as well, but that can be derived directly from the above info.

maybe I could use the autoConfig method or .cfg file along with getenv(), but I
haven't been able to get those methods to work yet (and getenv() is not
available in from .js files.)
