Found it i thought this only applied to the Edgerole but it looks like HUB is ok with it also...

Set-RecipientFilterConfig -RecipientValidationEnabled:$true

enable antispam filters on the hub:

Hi,
You can install anti spam agent on Hub transport server as follow:
- Close Exchange Management console
- Open Exchange Management shell and type commands:
  + cd "\program files\microsoft\exchange server\scripts"
  + Install-AntiSpamAgent.ps1
- Restart microsoft exchange transport service
- Open Exchange Management console: Organization configuration > Hub transport > tab Anti Spam exist.

I've tried this and recipient filtering doesn't work. I've got Antispam tab, I can enable, disable everything on it but my server still accepting mail to non-existed users. What can I do?

I've discovered that it doesn't work only for one of my two domains. On second domain it works fine. Why is it so? Can somebody tell me where to go?
