Sun managers,
Not long time ago I posted that the sendmail did not work after I installed DNS. Many people sent me suggestions :-), they are:
Bismark Espinoza [bismark@alta.jpl.nasa.gov],
Ade Faleti [afaleti@dllr.state.md.us].
Shouben Zhou [zshouben@PCS.CNU.EDU]
Karl E. Vogel [vogelke@c17mis.region2.wpafb.af.mil]
Kun Li [likun@bjaimail.asiainfo.com]
I solved by:
1.  Adding a root domain server in our LAN ;-)
2. Delete the DR and CR definations in mail servers sendmail.cf to avoid deep loooop.
3. Add DM and CM definations in both mail server and clients.
Thanks a lot.
Lin Yu.
BTW, I am from china and Lin is my family name. 
The origion is:
