Judging by the last delivery date is compromised by spam. Getting
mail unfortunately does not mean the account is being used.

Judging by seen state is much better provided you can assume IMAP.
I don't think POP updates seen. But POP devices tend to check in
regularly, so you could cover obvious cases by checking the last
couple of weeks of system log. It won't be perfect.
