Poll sender address is always the email of the admin

When one of our Nextcloud users creates an anonymous poll, the sender address is always the email of the admin and not the email of the account user. Is this setting correct? It confuses many?

Also, the poll will not appear in your account after participation

We use Nextcloud Version 18.0.6
Poll App is the latest Version

I got an answer about this via Github. This setting is correct. “NC sends mails via the configured mail system.”
