FYI....I've just had someone from "eo.npa.org" subscribe to my list. They are apparently using "Novell_GroupWise" software for email. So far every message sent to that user from my list has generated a "The message that you sent was delivered to the following address: [log in to unmask]" "Information about your message" Subject: (some_topic_on_the_list) Message-id: <[log in to unmask]> to my error account (owner-pmail). I was thinking about setting this userid to NOPOST but I would still get "Your message delivered...." mail messages for each posting _they_ received. Hopefully this is an option which they can turned off....but until I hear from them I've decided to delete this account from my list.
