I've a question about sendmail 8.13.3

After tried mail to root, the root can got the mail no problem, but the below message would shows in /var/adm/syslog/mail.log. Does anyone know what's the meaning of "reject=501 5.1.8 Domain of sender address root@hwae7620 does not exist" . And any error on sendmail ?
Thanks in advanced.

Hi
Did you check name resolving (hosts,nsswitch,dns)? Did you check relay settings in sendmail?
