They don't know enough, and probably won't even haver permissions. In any case probably most login processes have connections to all servers (assuming you don't have *that* many of them), so it would be pretty much equivalent to "killall imap-login".

doveadm kick is also a bit evil way to do it when using multiple connections per imap process.

Not really possible, because director doesn't keep track of usernames, only the hashes of usernames. And a hash list probably wouldn't be very useful.

I suppose it could get a list of all users and then list all users whose hash matches what director has.. Hmm. I guess that would be usable too, yes. :)
