I'm in the process of migrating a Mailman mailing-list of about 500 subscriber addresses from one server to another. The list-owner is an NGO and I'm not sure about the carefulness by which the addresses were collected. So as the first thing after migration I want to confirm the opt-in status of every subscriber.
I intend to send a first newsletter telling everybody who wants to remain on the list to re-confirm the subscription by clicking on a confirmation link.
Can this be done with Mailman? If yes, how do I create those links, how do I check the confirmation and/or what is the preferred way to go?
