[Dovecot] Detecting unused accounts

[Ben Beuchler]

I'm looking for a way to figure out which accounts have not been logged in
to in over n days.  It occurs to me that, perhaps, the way to do this
would be to look at the mtime on one of the dovecot-maintained files, like
'dovecot-uidlist'.  Is there a particular file that would be modified on
(almost) every login, whether it be via POP or IMAP?
