I have mail server via postfix 3.3 running on ubuntu 18.04.

When i’m sending mail from mydomain.com it goes to spam in google.
But the problem is, that before this error - i could get messages in google INBOX.

Here’s the fail error from google spambox:

Hi there @nampizdablen,

It might be something in your mail content that is triggering the spam filter.

What I could suggest is sending an email to the Mail tester website here and then checking the report:

https://www.mail-tester.com/

It would provide you with some good tips on how to improve your mail deliverability rate.

Hope that this helps!
Regards,
Bobby

Check if your server’s ip is blacklisted (http://multirbl.valli.org/)
DigitalOcean is a known source of spam, apparently nobody cares in DO to fix this… just need to add a few limits to new accounts
