As root run "systemctl edit dovecot.service". This will create a drop-in configuration file in /etc/systemd/system/dovecot.service.d/ which will be appended to the one in /lib/systemd/system/ during startup. The content should be ----paste-below----------8<--------------- [Service] LimitNOFILE=8192 ----paste-above----------8<--------------- Then a swift "systemctl daemon-reload" followed by "systemctl restart dovecot.service" should fix your problem. Attention: Do *NOT* follow anyone advising you to copy the whole systemd.unit from /lib/systemd/system/dovecot.service to /etc/systemd/system, as this will/may break your system after an update to a new Debian version in the future.
