How to configure mail?

Good afternoon.
We have to Google most of the letters gets in spam.
On the recommendations of the same Google set up dkim, spf, dmark.

In Yandex and Google now says that the sender is confirmed.
But the stash doesn't turn green

Post itself is on your server.
And mail on Google it will continue to go in spam.
Why this could happen?

And the second question, the part is sent from the web client roundcube, and the other part with e-mail software, Outlook.
And then in the field Received: from [10.12.18.115] - is the ip address of the computer which made sending.
And the spf recorded the address of the mail server permitted to send also the address of the relevant A and MX records.
How to configure your mail client to the sender field was the ip of the mail server?

Thank you.

1. the domain name is not a secret since you still pay money to its advertising, stop to play in the KGB.
2. the name of the domain in the signature this moment is critical for this samotarev it, you have overwritten part of the question.
3. And where's your spf? or is he also a secret
if you want the answer stop playing spies and share data especially since they are available online and are not secret
DKIM that part a secret ;)
But DMARC has no
