When upgrading on Debian Stretch with the security fix packages all dovecot processes get killed and then restarted despite having "shutdown_clients = no" set.
This is systemd doing its "magic" (kill all control group processes), see https://dovecot.org/pipermail/dovecot/2016-June/104546.html for a potential fix.
Actually that will not be enough in the upgrade case as the maintainer script calls deb-systemd-invoke stop dovecot.socket dovecot.service
I personally think re-connecting clients are normal operations so I wouldn't bother. But you could override the stop action in the systemd unit if you have local reasons that warrant such a hack.
