My mail goes to spam, even if i have spf and mx record.

I have mail server via postfix 3.3 running on ubuntu 18.04.

When i’m sending mail from mydomain.com it goes to spam in google. But the problem is, that before this error - i could get messages in google INBOX.

Here’s the fail error from google spambox:
