The thing is, he doesn't have ROOT on ducks. Ducks is just the mail 
machine he has a shell account on. How does using procmail to forward 
the email get him anywhere?

Now, obviously, he could have the two other addresses forward to his 
account on ducks, and then use procmail to deliver them to different 
mailboxes in his home-directory. The trick, though, will be getting binc 
to actually authenticate his users properly.

Come to think of it, if you write your own checkpassword script, that 
may not be so bad. Just have it check the validity of the provided 
password, and then set $USER, $HOME, and $SHELL and so forth. Check out 
the description of checkpassword here:

It's reasonably easy if you're a bit of a coder. Can even be done as a 
shellscript.

Uh, because he doesn't have root on ducks?

Yeah, except for the "doesn't have root on ducks" part.
