Mail from same server, different domains going to Junk and Inbox

Hi,

I have 2 virtual servers on my VPs and one can deliver just fine to inbox, now the other one I created after, delivers to Junk…

I’ve set up DKIM and SPF on both, same DKIM key.

Do I need to set up different DomainKeys identified mail for each site? or what could be the reason, both domains use the same ip address as they are both on the same VPS…

Thank you!
