strange mail behavior

Hi all, I have a number of identical virtual Linux machines (All RedHat Enterprise AS release 4
(Nahant Update 8)) and on one of them, invoking the 'mail' command generates an error, although the
command itself gets executed correctly. This is what I mean:

[root@overlook mail]# ls|mail -s "test" ycsapo@mines.edu
Unknown command: ""

But I do receive the message. To compare, here's the same thing on one of the other boxes:

[root@trailhead ycsapo]# ls|mail -s "test" ycsapo@mines.edu
Null message body; hope that's ok

And I also receive the message. By the way, I see the same thing even if I invoke mail all by itself
with no params.

I can't find a difference in configuration between the boxes. Any ideas where to look?

Thanks

Yuri

The idea that an arbitrary human should be able to properly use a given tool
without training or understanding is even more wrong for computing than it is
for other tools (e.g. automobiles, airplanes, guns, power saws).
