Well I used to be able to do this.  Is this a 5.x design?
How might I be able to get it to work the way it used to?

This behavior doesn't seem limited to root.  but to kib and virtualuser as 
well.  I can only assume hat it applies to any alias or real user.

My mail host is qmail/vpopmail.  Actually its Matt Simerson's mail toaster 
at http://matt.simerson.net.  My local-host-names is actually a mysql table 
and considering the number of machines involved this is going to be a 
difficult task to maintain unless I can find a way to use some sort of 
globing (*.domain.com or such).  Although this problem is for the toaster 
mailing list to assist me on if it comes down to that.

This mail host is set to accept all mail for kibserv.org and example.com.  
Both are test domains.  It seems to receive mail just fine when it gets 
postmaster at kibserv.com but not say postmaster at host.kibserv.org.  Actually I 
don't even think user at host.domain.com ever gets to the mail host...if I dig 
for mx records on host.domain.com it comes up with no answer and the default 
for sendmail it to send mail directly (basically to localhost) when no mx is 
found.  So I suppose a work around would be to add an mx record for every 
host but that doesn't seem like a clean solution to the problem.

Good point.  I will reconfigure as you suggest.  The cname mail.kibserv.org 
is mainly useful for getting web mail users to the proper place.
