The mailservers on an intranet should never be allowed to send mail directly to the internet through the firewall. Instead they should be setup to send mail to a mail hub (either on the firewall/another system). The mail hub would then have its name in the public DNS. NOTE: It would also be the only system that would receive mail from the internet. Scot To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
