Question Block outgoing email from domains that are not hosted.

New Pleskian
Hi,

I want to block all outgoing mail on our Plesk server that are using from email addresses that are not hosted on our website. Is there any simple way to achieve this in postfix? I've already tried updating smtpd_sender_restrictions, but that blocked all incoming email for some reason. Can anyone help me with this?

Kind regards,
Bas Milius
