Re: sendmail - host unknown
You don't have DNS hostname resolution.
Check /etc/nsswitch.conf to see how host resolution is done.
If DNS is first then check /etc/resolv.conf and make adjustments until commands like nslookup hp.com work and provide you an answer.
Your internal mail setup may require that you relay mail through a firewall or exchange server. This is done with the DS directive in sendmail.cf, followed by a restart of sendmail.
Note though that the server you point to in the DS directive must specifically be configured to allow relay from your hpux host.

Re: sendmail - host unknown
as for the sendmail.cf file, it is a copy of a file working on another hp-ux server.
thanks in advance.

Re: sendmail - host unknown
hosts: dns [NOTFOUND=continue] files
ipnodes: dns [NOTFOUND=continue] files
Test your name resolution with nslookup, for example:
nslookup -query=MX company.com
