[MM3-users] Migrating from old V2 server to new V3 server. Questions.

We have figured out how to migrate from one server to another, but after removing the list from the old server, the e-mails are still trying to go there. Is there something that needs to be done in mailman so that the e-mail list will hit the new server instead? Does it just take time?

Thank you, Joe Koral
