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.

YMMV
