    Is the default gateway and dns set up properly? On the HPUX systems if you do
    do you get
     Non-authoritative answer:

    For the gateway use "netstat -rn". Do you have on the first line of the left most column gateway, and is it pointing to the right place?

    Next try sending mail to anyone with the -v option and post the result
              mail -v

    Are you using an internal mail forwarder (firewall, or spam filter or ?)?
