Is there a way to possibly tell Dovecot to refresh the mod time on an index file whenever the user successfully auths or to refresh a separate file in the homedir, ie: ~/.lastlogin  (not ~/Maildir/.lastlogin as that would obviously cause some issues)

i have running touch with 3000 users, i dont see much overhead, anyway
its true ,its not very elegant, perhaps i.e you may write some daily
cron bash find script looking about latest timestamp of files in .new
with maildir
which of cource is not the same as last_login script, but may good
enough for you
