My issue has been solved by Digitalocean support team, Thank you all Who tried to solve my issue…

Support speed is really horrible

I was on the same boat, after a couple messages with the support team, this fixed it:

sudo ufw allow 25
sudo ufw reload 

You’re not paying enough for a support SLA, it’s best effort, can take up to 48 hours.

iptables -I INPUT -p tcp -m tcp –dport 25 -j ACCEPT
