You're splitting hairs.  No it's not technically legitimate mail to a 
current user.  However it could easily be (and often is) mail which 
is not spammy in content and should not be considered spam, as other 
legit users on the system expect mail of this type and expect it to 
come through (sometimes duplicate copies of the same, as in mailing 
list email).

If I were to leave, for instance, then all email from this list and 
many others would be funnelled into the spam corpus.  Presumably the 
person who takes over this position would join the list(s), and list 
messages to them would be rejected as spam.

Granted, they should be able to figure out what's up and fix it with 
a whitelist entry, but what if a similar scenario happens with a 
"normal" user?

Maybe it's just been a long day and I'm not getting it, but I don't 
see how that would solve my scenario above:  List mail comes in, 
checks as good against spam db, fails LDAP on the expired user, and 
gets added to spam db.   Next list mail comes in, fails check against 
spam db, and the legit mail to legit user gets bounced. Sounds like 
you'd be messing up your spam db pretty quickly to me.
