domain is blocked

[Ярик Швиденко]

My domain is blocked for sending emails to gmail. Could you tell me what to do in order to remove this restriction

Hello,

Can you tell me more about your domain and how it is being blocked? When did this start? We need this to have basic information.

Hi Elliott. The domain name of my mail service is ngu.gov.ua. Gmail blacklisted it after spamming mail started on its behalf. This happened during the firewall replacement. For a while the service became available on many ports, after which we were hacked.

Hello,

since your question requires more specific troubleshooting I would advise to post your inquiry on https://developers.google.com/issue-tracker.
Google Groups is used to discuss higher-level concepts, where Issue Tracker is used for bugs and situations which require specific troubleshooting. Additional information may be required privately to correlate your domain to the GCP project and App Engine instances linked to the domain.

I think that the steps and troubleshooter linked here would be a better place to start. Folks in GCP Support are not likely to be able to make changes to GMail deliverability.
