If I have missed anyone, I apologize.

This turned out to be rather straight forward. I needed a way to have my 
main mail system handle mail for multiple domains for users on my 
system.  The enduser could be either a user directly on the system or a 
dialin POP3 user.  I was not too concerned about having the system look 
like any other domain on outgoing mail as the majority of my endusers are 
POP3 users and they could configure their return address to reflect the 
different domains.

The solution was to download the Berkeley V8.6.12 from 
ftp://ftp.cs.berkeley.edu/ucb/sendmail, print out the Postscript manuals 
and follow the instructions to configure the proper .mc, .m4 and .cf 
files to read an external file that contained the domains that I wanted 
the system to recoginize in the "Cw" macro.  Then I created the 
individual DNS zone files with the appropriate MX records.  Viola, all is 
done.  

The docs are very well written and do explain things quite well.  I also 
got some good suggestions out of the following books that I picked up :


"Sendmail", O'Reilly and Associates, ISBN 1-56592-056-2
	Bryan Costales with Eric Allman & Neil Rickert

"Sendmail Theory and Practice", Digital Press, ISBN 1-55558-127-7
  	Fred Avolio, Paul A. Vixie
