Being clever about sending mail

[Charles Rich <RICH at MIT-MC>]

In System 79.52, ZMail 40.7, Remote-File 2.0, LMFILE-Remote 5.3,
Obsolete Tester 23.7, Reasoning Utility Package 1.0,
Experimental Plan Calculus 2.4, microcode 849, 79.49 PC 2.4, on Lisp Machine Twenty-two:

If the associated machine for a LISPM goes down (typically AI)
after I have logged in, I have a terrible time getting ZWEI in
the Mail command and also Zmail to use another available host
(e.g. MC) to write out the mail queue file.  I have tried resetting
ZWEI:*MAIL-QUEUE-FILE* and all kinds of other things in sight,
including logging out and logging in again (LOGIN 'RICH 'MC)
and so on and still usually end up losing.  I don't really want
to cold boot the machine, which seems like the only way to get
all the relevant internal state reset.  This happens quite
often and is very frustrating.  It would be nice if the mailing
code were written a little more cleverly, e.g. to try sequence
through entries on ZWEI:*CHAOS-MAIL-HOSTS* until it finds one
that is up.
