Postfix virtual domain address not working

I have a VPS running Ubuntu 20.04 LTS and postfix installed. Emailing is working great with the real hostname and suffix, but receiving mail from outside (like from gmail) to virtual adresses wont work.

Real hostname mailbox ([email protected]) receives email ok from outside.

Also sending mail inside server to virtual address works ok.

echo "test message" | mailx -s 'test subject' [email protected]

Sending email from gmail gives an "Relay access" error.

Mail Delivery Subsystem: <[email protected]>
Subject: Delivery Status notification (Failure)
554 5.7.1 <[email protected]>: Relay access denied

server hostname

domain.name.net

mx records

dig mailserver.com mx

This is solved now. We didnt have any MX records on VPS provider side. After adding correct ip+domain records everything works.
