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. To: [log in to unmask]
