[Sorry if this post appears twice. My original post sent yesterday still does not seem to have made it to the list.]

I need to move a LISTSERV list to a new listserver. The main hurdle to moving to Mailman is the fact that Mailman lacks the ability for authors to confirm their own messages. The principle is similar to the way Mailman confirms new subscribers, with a web-based message confirmation link emailed to the subscriber. Is there a hack somewhere for adding this confirmation feature for messages? The fact that Mailman already has an email confirmation ability for subscriptions built-in suggests to me that someone, somewhere has figured out a way to use that facility for message confirmation.

For those who are interested, we implemented message confirmation on the LISTSERV list as a security measure. We did not want to use moderation because that tends to slow down the discussions and the dissemination of urgent information. But at the same time we wanted a way to prevent non-members from spoofing a list member and getting their offensive postings out to the list. The list is an invitation only list, so once a member is on the list, they are trusted enough to post freely to the list
