I have same issue in OpenVZ Ubuntu 20.04 with two IPs and clean installation. It also not start dovecot and exim4!

I test ExecStartPre but not worked. I used this in crontab, it is dirty but it works!
@reboot /bin/sleep 20 && /etc/init.d/apache2 start
@reboot /bin/sleep 20 && /etc/init.d/nginx start
@reboot /bin/sleep 20 && /etc/init.d/dovecot start
@reboot /bin/sleep 20 && /etc/init.d/exim4 start
