Hello All,

We have been running Greylisting since mid December 2003 on multiple 
MX's with a centralise Database, and are currently very happy with the 
Spam has been reduced from about 50% to around 10% (when implemeted on 
all MX's)
    We have about 2500 users...
    Currently are on about 2,500,000 id...
    Dumping about 30,000 to 40,000 expired records a night

But we have over this period identified some ill-configure relays out 
there which we have had to "whilelist" , yahoo etc .... Currently ~45 
whitelisted servers...

Has anyone done any work on trying to identify valid MX's that require 
whitelisting from the database contents... Since we are still concerned 
about not receiving valid mail....
