Question restrict direct (incoming) mail delivery for certain domains

New Pleskian
HI folks,

I have multiple domains on my plesk onyx (Ubuntu) server and some domains retrieve their mails from a filter service.
Is there a way to configure postfix/dovecot in a way that some domains accept incomming mails only from certain IPs and others from every IP?
From time to time some spammer managed to deliver directly to my server and avoiding the filter service.

Thanks for hints in advance.
