The first list i create, even if i got the same error, works very well. The other lists i create are able to sends massages, but whe i try to write to list@domain i receive a MTA error saing that the local user doesn't exist... I'm sorry if i write in the list with a bad english and without waiting some days after the subscription, but i absolutely need the list working in few days. Thakyou very much, Tommaso
