REPLY TO 01/14/87 12:32 FROM [log in to unmask]: Mail and changing userids
 
Eric, at least, should certainly know all the sites that are
running his LISTSERV (hopefully there soon won't be any others).
If he keeps a file on his machine it would certainly seem possible
to write a program which uses it to allow the postmaster to send
a command to all remote LISTSERVs requesting that any of the listed
userids from his/her node be deleted.  If that seems to open too
big a security hole (i.e. can someone fake being the postmaster?)
then it could at least generate a letter to all of the remote
postmasters requesting that it be done.  The remote postmaster could
then verify the request according to local security conventions.
