Probably not; no.

Nope, just probably one of them (read on) ...
 
Wendy (just you, not every lstown-l subscriber!):
 
Send each an individual e-mail with a unique Subject: (perhaps their
name/userid).  Try to stay "logged on" to see if any bitnet
(progress/status) messages are returned to you (Mailers will sometimes
provide you with valuable insights via interactive Bitnet messaging).
 
See if any bounce.  (My initial take is that one of them has e-mail
forwarding turned on.)
 
OR, follow this advice (particularly paragraph #2 which implies that you
can FINGER [log in to unmask]) abstracted from the _FAQ: College
Email Addresses 3/3_
 
Univ. of Michigan:
        The best place to try to find an e-mail address for a faculty,
        students, and staff at U-M is via the X.500 White Pages service.
        There are many ways in which this can be accessed, but one easy
        way is through finger (finger [log in to unmask]).
        (The X.500 Directory also contains business addresses, business
        phone numbers, titles, and home addresses and phone numbers in
        the case where the person has granted such permission.)
        If the person has registered an e-mail address, it will appear;
        if the person has not, follow the advice of the X.500 server and
        try fingering the person at um.cc.umich.edu (the mainframe),
        caen.engin.umich.edu (the College of Engineering mail hub), or
        med.umich.edu (the Medical Campus mail hub).
 
        People with accounts on um.cc.umich.edu also have a Bitnet
        address:  [log in to unmask] where 'xxxx' is the person's
        account on the mainframe.
 
        A database of U of Michigan student and faculty phone numbers
        and addresses (not email addresses, just phones) is available through
        the "gopher" server running at gopher.uis.itd.umich.edu port 70, also
        available via telnet to gopher.micro.umn.edu (login: gopher) in the
        "Other gophers" menu or the "phone books" menu. This gopher
        phone number database has been changed to access X.500.
 
        Grad students in EECS get accounts on eecs.umich.edu. (The
        specific machine names are dip and zip, but eecs forwards
        appropriately.)
 
        Usernames are either lastname, or of the form Fname_Lname.

        If all else fails, you can always mail the request to the U-M
        postmaster at [log in to unmask]
 
        Alternately:
                telnet to 35.1.48.149 35.1.48.150 or hermes.merit.edu
                press return until you get a "Which Host?" prompt
                type FINGER UM <return> NAME <return>
                to get finger information for NAME
----------------
I believe it is your 2nd listed userid that has the problem.
Alternative e-mail address(es) might exist.  Use the other
techinques listed (incl. gopher) to find them.
