a) localhost is resolved in /etc/hosts, mail.babbnet.com is resolved in dns. b) connection to mail.babbnet.com goes through different interface and some traffic (maybe tcp/113) is dropped by firewall rules. if you are unprivileged user on server and can change globally used dns server's without any help from tech support - change your provider. /etc/resolv.conf is not supposed to be world writable. -- Tomas ------------------------------------------------------- Using Tomcat but need to do more?
