Yes, I'm familar with the aliases file - but that won't allow duplicate 
names based on domains. I found some good info on all of this stuff at:

http://howto.linuxberg.com/LDP/HOWTO/Virtual-Services-HOWTO.html

I'll probably end up just doing the virtual FTP - everything else is
just
a little more elaborate then what we need to accomplish. 

I may look into doing the Sendmail stuff - time to open the O'Reilly & 
Associates bat book. :-) When in doubt - crack the O'Reilly stuff.
