The address [log in to unmask] is a LISTSERV alias. Your MTA passes the message to LISTSERV, which distributes it to all non-quiet list owners. Unfortunately, there does not seem to be any way to prevent anyone, anywhere from sending anything to that address. Unless you want to provide spammers and other malicious mailers with a route to all your list owners' mailboxes, you will disable this alias and find another way to reach your list owners. We maintain an announcement list for our list owners. The list is refreshed as needed using a script which greps the "owner=" records from "listview" output and submits a bulk add job to LISTSERV. I am willing to share the script with anyone who is interested. We run LISTSERV 1.8d on Solaris 2.8. -- Paul Russell Senior System Administrator O&E Messaging Services Team University of Notre Dame
