Seems Port 25 is blocked by DigitalOcean. I can’t change VPS provider. Seems they don’t open the port even when you request.
What is other free way to send emails? I maybe like to need to send 2 or 3 mails per day. Will zoho’s free business mail work or any other free alternative?
Oh btw domain is behind cloudflare tho and using plesk panel if required to know for this topic.
