It is the incoming and outgoing SMTP server. It's the only one we have. -Jim _______________________________________________ Yes that may be the only one you have, but that does not stop the user from configuring their outlook express from using their personal email account at their ISP. To stop this you can add firewall rules to deny all LAN traffic out to ports 25 & 110 by coding the private LAN ip address range in the rule "from" option. Since your SMTP service is on the gateway box where the firewall is your outbound port 25 will pass because your using the public ip address or if that is not the case then just add a rule before the deny rule to pass your SMTP LAN ip address. o unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
