There are other reserved domain names for local or test use, too: "localhost" "test" You could use localhost as a top level domain (separate to the sole "localhost" used for 127.0.0.1), e.g. fedora3.localhost. Though some things apparently don't handle that well. You might be best using the "test" one. e.g. fedora3.test -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
