Why do emails from my mail server go to google spam?

Question

gmail

Hello,
To send letters from the site, a mail server was raised.
Dedicated ip, PTR record is registered by
SPF and DKIM is configured.

Authentication-Results: mx.google.com;
spf=pass
dkim=pass

The IP-address is not in spamhaus.org spam lists
. Letters go to mail.ru, yandex.ru normally, they do not get into spam.
gmail and google apps stubbornly consider this spam, who has come across? Where to dig?

Answer 1

By the way, we have the same problem here. I don't know what to do anymore. Both SPF, and DKIM, and DMARC, PTR are normal, there are no spam databases. But it still falls into spam, regardless of the text of the message and the recipient's mailbox in gmail.com

Answer 2

Are From and smtp.sender fields the same?
is hostname correct on the machine?
Show the header of the message that got into spam in its entirety, in general.

Answer 3

1) the letter contains links to external resources, for example, pictures from the forum.
2) emails from this sender and server were clearly marked as spam by recipients.

Answer 4

Is the PTR the same as what your HELO/EHLO mailer gives you when you connect to Google?
