[Dovecot] Disconnect users for a distinct period of time?
Hi --
Today, I've learned who to disable incoming mail delivery to dovecot (accepted by postfix), temporarily. Now, I would like to know if there is a way to make a "doveadm kick -A" a permanent disconnect until one would allow reconnects, again? This should be done *without* shutting down dovecot or *extensive* re-configuration. A "doveadm block -u <joe> -m 'sorry: running maintenance, please, come back later'" alike tool/funtionality would be ideal.
Background: I would like to avoid any modification of my user's maildirs by a running dovecot server while modifying maildir formats, mdbox_rotate_size setting, and alike, where I would need doveadm/dsnyc access to userdb. (I know there a ways to achieve this without downtimes, and I have already done so.)
I just want to be sure that I haven't overseen such a tool/functionality in the documentation. Did I or didn't I?
Thanks and regards, Michael

I think this can be done with post-login scripting, where a script checks if the user is allowed to login. http://wiki.dovecot.org/PostLoginScripting

What I've been doing so far, is I configure dovecot 2.1 with a deny-hosts file (in auth-deny.conf.ext) and then I can append a name to that file to block them, and remove them to allow them back in. Since this file is a simple text file with one username/address per line, it is very easy to manage.
No idea if that would work for you, since your usage is for a different reason than mine.
