Might I suggest doing something on the "outbound" or SMTP-authenticated 
mail, similar to anthony howe's milter-abook, that just gathers addresses 
of "known" email contacts?

Given this doesn't give you access to historical data (which might be what 
the original poster wanted), but over time it could provide a much more 
useful corpus and as a bonus it works regardless of what addressbook 
storage methods your clients are using, so long as they're sending via 
smtp.
