$ mkdir -p /etc/systemd/system/dovecot.socket.d
$ vim /etc/systemd/system/dovecot.socket.d/ports.conf

content:

[Socket]
# unset all ports defined in the global file
ListenStream=
# add our new ports
ListenStream=[1.2.3.4]:143

$ systemctl daemon-reload
$ systemctl restart dovecot.socket dovecot.service
