hi, Gurus,

I need some help with sending mail out from my UNIX server:
It is running Solaris 2.6 and the sendmail version is 8.8.
Output of :/usr/lib/sendmail -d0.1 -bt < /dev/null

Version 8.8.8+Sun
Compiled with: LOG MATCHGECOS MIME7TO8 MIME8TO7 NAMED_BIND NDBM NETINET
NETUNIX NIS NISPLUS QUEUE SCANF SMTP XDEBUG

============ SYSTEM IDENTITY (after readcf) ============
(short domain name) $w = my_server
(canonical domain name) $j = my_server.my_companydomain.com
(subdomain name) $m = my_companydomain.com
(node name) $k = my_server

ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>

When I ran "mailx/mail" , it gave me " User Unknown" error and save my message into a dead.letter. Can somebody tell me what do I need to change in my sendmail.cf file? My only purpose is trying to send file in this server to somebody in my company's e-mail account.

Message from syslog:

Nov 19 13:48:07 my_server sendmail[9885]: NAA09885: to=somebody@my_company.com, delay=00:00:00, mailer=relay, stat=queued


Thanks!
