Error logs with virtual folder after upgrading to 2.3.4

If you are using systemd, you might want to create

/etc/systemd/system/service.dovecot.d/override.conf

with 

ProtectSystem=no

if you want writable /etc directory.

I have also tested to create an emty file with userid entrega in
/etc/dovecot/virtual/ and works, so it does not seem a problem with permissions.
Any idea about this problem?

easiest way to create it is:

Dont you need?:)

No need to disable everything just for that. This should be enough:

[Service]
ReadWritePaths=/etc/dovecot/virtual

Also you can use `systemctl edit dovecot.service` to let systemctl
handle the file name and daemon reloading. Assuming you have a recent
enough version, but I think that feature is kind of old.
