You need two things to make this work: (1) your internet nameserver/forwarder
must either supply an explicit MX record for each subdomain name you
add or a wild-card MX that will allow you to add anything you want below
your own domain name, and (2) your mailer must recognize the subdomain
names and route them correctly via uucp.
I recommend smail 3 as the solution to the latter problem - it will
compile under SysV and do exactly what you need.

If you are using uucp over starlan, your mailer won't know the difference
from any other uucp transport.  If you are currently using any of AT&T's
PMX mailers, I have some hacks to smail 3 to add the "Content-Type:" and
"Content-Length:" headers and a few other things to keep it from getting
confused.  Let me know if you want them.
