Our machine is running Solaris 9 and using NIS. I sshed in as a regular user A
and "su -" to root user. I typed following command as root user "mail A test
ctrl^d". I switched back to regular user A and checked the email of A. I found
the email with the content "test" as expected but I found the sender of the
email is A NOT the root. I am wondering why I issued the mail command as root
but the sender is not root but user A?
Thanks in advance! | w**n

Yes. /var/mail is NFS mounted.
cat /etc/mnttab|grep var
auto_direct /var/mail autofs direct,ro,nosuid,ignore,dev=3dc0001
1080130613
/export/mail /var/mail lofs rw,suid,dev=800080 1083962476
Could you tell me why it matters since /var/mail is NFS mounted?
Also, I have two more questions:
1. What is /export/mail. is this a local partition?
2. I am not sure the meaning of lofs. Does it mean a file system on local
disk,
if so, why didn't use /dev/dsk/... We only use NF

lofs is loopback virtual file system , you could man lofs get more info.
