Obviously your concerns are a little overblown, as others have already 
pointed out.  In the spirit of TMTOWtDI, I wrote a very small finger 
daemon which runs on our primary server (which contains the vpopmail 
virtual domains/users).  The inbound MX boxes can perform a very quick 
check via Net::Finger to validate any address (I can even tell the 
difference between an actual address, an alias, and a list).  The 
returned data is < 256bytes, so it is a very low overhead system, and I 
am running the daemon under tcpserver, so only the hosts I specify can 
even make finger requests.


This is by far the best solution I heard about. Can you provide that 
daemon to the public?

The solution is great because such a daemon could be configured per the 
kind of installation the user uses. Some people use vpopmail with ldap, 
and some (like me) use vpopmail-mysql. And then you can never really 
escape the .qmail-* files which specify bounces/aliases/scripts. It 
seems like they are there to stay, at least for now.
