Recently watched https://en.m.wikipedia.org/wiki/The_Act_of_Killing so no longer suprised by anything happening in Indonesia. 💀

The domain name doesn’t matter at all. The really important thing is the IP of your MTA (the server sending mails). Eg. if it was previously used to send spam you need to get a new one from your server provider, as it will be blocked everywhere. Also the server configuration needs to be good. Use dkim, dmark, spf, mta-sts, etc.
