Emails with vds end up in spam, what needs to be changed?

Question

Fight against spam

Good evening! Made a mail server on VDS, but the mail gets into spam. Checked through the mail-tester.com service. And I found out the following ..
Can I improve something here?

Этот отрицательный рейтинг станет положительным, если подтвердить подпись. Как это сделать смотрите ниже.
0.1	DKIM_VALID	Message has at least one valid DKIM or DK signature

You need to ask the hoster this, maybe they can help "whiten" the IP, otherwise you need a new one.
