[Dovecot] Automatic expire on post-login

[Antonio Perez-Aranda]

Yes, -A is a typo error, because a I copy from cronjob. Really, I do
doveadm -u $USER.

Well, I use expungestamp if the overload is very high.

When I execute doveadm -u $user many times, it's not take much time,
lower than 0.1 seconds.
