no mail from / for root

[j_70 at comcast.net]

I guess the curiosity here is that:

[root at rhel1 root]$ ps -aeef | grep mail
root   19005 18945  0 20:23 pts/0    00:00:00 grep mail
[root at rhel1 root]$
[root at rhel1 root]$ ps -aeef | grep master
root   19081 18945  0 20:24 pts/0    00:00:00 grep master
[root at rhel1 root]$

Yet root has 123 messages. Where are they being served-up from????
