If you want to redistribute your mail to your local users you have to use procmail and make a .procmail file like this: :0 *^TO.*joe* !joe :0 *^TO.*jim* !jim .. and so on... where joe, and jim are local users. do man procmail to learn more about it. BTW: I've been using this setup for a long time and it WORKS!!!
