Problem with the command mail

[Toll, Eric]

Greetings all, I have a problem with my AMD64 FreeBSD server
which is:

FreeBSD rodan.vipstructures.com 5.4-RELEASE FreeBSD
5.4-RELEASE #0: Fri May 13 12:55:54 EDT 2005
eric at rodan.vipstructures.com:/u
sr/obj/usr/src/sys/HAMMER  amd64


When I used the command 'mail' the system does NOTHING.  I
don't know what I did or did not do to break this.  System
is running Postfix flawlessly.  System can also run sendmail
with out any issues.  Below is a paste from my term session.


[eric at rodan]/home/eric(100): su
Password:
You have mail.
[root at rodan]/home/eric(101)# mail
[root at rodan]/home/eric(102)# mailq
Mail queue is empty
[root at rodan]/home/eric(103)# which mail
/usr/bin/mail
[root at rodan]/home/eric(104)#


When I login as root, system tells me I have mail, yet the
file /var/mail/root is empty.

Any pointers or tips would be greatly apprecaited. 

TIA
Eric
