All my email goes to spam in GMail, Hotmail

[WMan]

I set up my server but all of my emails that I am sending to gmail goes to the spam folder.
I checked my domain using dnsinspect.com service and it pass mx and mail tests.
This is the header of the email that goes to the spam folder:

https://cloud.openmailbox.org/index.php ... O3IBdteDHQ
The password to open text file is: 385231


The PTR record goes to mydomain.zone
Should I change it to hostname.mydomain.zone ?..

Please help me I do not have any idea what to do...

Is your server hostname ''hostname.mydomain.zone'' or ''mydomain.zone'' ?

[WMan]

just mydomain.zone

Should I chnage it?..

If yes how to do it in the right way?..

Is that any rules about hostname or I could use any?..

Thank you in advance for your help!

If your hostname is mydomain.zone, and PTR record is mydomain.zone - it's OK !

Send email to GMail and give us a mail header from GMail.
GMail has simpler header, easy to find what's wrong if something is wrong.

for now I've put hostname.mydomain.zone but that the result is the same.

This is header from gmail.com

PTR should be equivalent as server hostname.

When I run in SSH: hostname
It will say for example: server.mydomain.com
Then PTR should be server.mydomain.com

Header from GMail looks fine.

Did you checked mail server score here - https://www.mail-tester.com/ ?
