Sorry, thought i had responded to this one ... It's already well discussed 
on the -core list, but, around the 25th, I went through some of the 
various logs and built up a list of 'no such user' and 'delivery refused' 
addresses and unregistered them, to clean off the lists of dead accounts 
... although I scanned through the list before doing it, I should have 
gotten a second set of eyes to look it over ... manual failure on my part, 
sorry :(
