Dear SUN managers,

Three responses have been got:

Jed Dobson <jed@wgtech.com> - suggesting either a name resolution or a NFS
issue

Buddy Lumpkin <BLumpkin@ijapan.com> - suggesting DNS resolution problem

DAN <dana@dtn.com> - suggesting DNS resolution problem

Summary: Yes, the problem is due to the missing
definition of the  SUN Ultra2 hostname in the DNS maps. 
(Instead, its alias name was defined in the DNS maps.)
It has been solved, and the mail commands function normally now.

Thanks alot for your kind and prompt advices.
Patrick Fung
