Answer 1

The IP address is in one of the blacklists, judging by the information from here - https://www.dnsbl.info/dnsbl-database-check.php
Everything is in order with your mailer, judging by the headers and the presence of a PTR record.

Answer 2

What does google say? If you open a letter from the "Spam" folder, then the reason for getting the letter there will be shown at the top.

Answer 3

As for Gmail, IP and/or domain reputation works there. If the domain was not highlighted in mailings, then most likely the issue is a tarnished IP reputation.
You can try to train Gmail to improve it through the actions of the recipients ("not spam", replies). But you will need several boxes.
