I came to this conclusion, too, but, so far, have been unable to get 
local delivery working, either.  I have tried running 'maIl marc' then 
filled in subject and body, then ended with CTL-D.  Is CTL-D the correct 
way to end the message and send the e-mail?  Is there something else 
that I need to do to actually send the message?   It may be that the 
various things that I have tried have borked local delivery.  What 
should I have installed and how should it be configured to deliver mail 
to my local user?

Clearly, I am doing something wrong, I just don't know what.
