Two domains, one MAIL server, how to make friends with Google's spam filter?

Asked bykim scarborough

On one server there are two projects on different domains:
nashitut.ru
energosi.ru

After a week of wandering around the forums and documentation Google, set up as follows:
The SPF, DKIM, DMARC records - google all of them are tested and the verdict is PASS (both domains).
MX records for both domains are shared - mail.energosi.ru
PTR record - mail.energosi.ru
mxtoolbox - all options with green check marks.

However, Google Mail puts the letters in SPAM, although all checks have been passed:
