False unless you dont want mail for your domain(s) at all. When a user wants to send mail to a domain NOT hosted by your mail server then you want them to authenticate to ensure that you are not an open relay, but incoming mail need not be restricted except to make sure that you are the MX for the domains. Make sense? Thomas
