TIA What do I have to do that my subscribers will get a message like this ? Sat, 16 May 1998 06:00:13 This message is a "probe" for your subscription to the PM-NEWS list. You do not need to take any action to remain subscribed to the list, and in particular you should not reply to this message. Simply discard it now, or read on if you would like to know more about how this probing mechanism works. A "probe" is a message like the one you are reading, sent to an individual subscriber and tagged with a special signature to uniquely identify this particular subscriber (you can probably not see the signature because it is in the mail headers). If the subscriber's e-mail address is no longer valid, the message will be returned to LISTSERV and the faulty address will be removed from the list. If the subscriber's address is still valid, the message will not bounce and the user will not be deleted. ...........................
