[X-Unix] how to send mail from commandline?

[Warren Pollans]

Hello,

When I try "hello | sendmail -fwarren at meyer-pollans.net 
warren at meyer-pollans.net" I get an error that indicates (from googling) 
that it wants/needs postfix - I'm on a G3 ibook (10.3.9)  -  the error 
is "... warning: unable to look up public/pickup ..."  I tried it this 
way because this is what works on my linux box

What's the easiest way to send mail from the commandline?  I'm trying 
to send the contents of a text file - this is the log from a series of 
tests that I've run - I'm having the script that runs the tests mail me 
the results.  I'm just trying to get things setup so that I can run 
from my ibook while I'm traveling


Thanks,

Warren
