You'll have to get cooperation from the remote machine.  Let's assume that
you are mailing to a remote machine that runs sendmail.  Then you can
get the remote admin to edit /etc/aliases and add a line like:

kernel: lm,auspex!guy,shannon,limes,glenn,dave at cs.wisc.edu

Then if you mail kernel at remote.host.whatever the message will be exploded
on remote.host.whatever instead of the local host.  

You may need to run "newaliases" which massages the alias file into a 
database that sendmail uses.

If you are sending to a remote host that doesn't run sendmail or any other 
mailer that provides an aliasing service then I don't know what you can
do.

This message is more appropriate for comp.unix.questions so I've directed 
follow ups there.
