Thank You For Your YouTube Tutorial on how to set up a Free SMTP Server with Postal, I’ve purchased the exact same droplet on DigitalOcean and followed the Tutorial, by the way, I’m a huge fan!.
I am having a problem after following all your Steps in the Tutorial, in the end when sending a TEST MAIL, I have this error don’t know what I’m doing wrong or if its DigitalOcean is blocking port 25 for new accounts??:
Thank You so much! I am needing so much this server for my modest campaigns, If you can help me as soon as you can I would be very thankful!
