IMHO you should NOT do it this way. This way ANYONE can define your mail server as a MX host for their domain and you will act as a relay for that domain. This is dangerous. What you should really do is modify relay_domains and explicitly state which domains you want to relay. e.g. relay_domains = $mydomain, clientdomain1.com, clientdomain2.com Regards, Simon -- Simon J Mudd, Madrid SPAIN Tel: +34-91-408 4878 email: sjmudd@pobox.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-newbies" in the body of the message
