Multiple Domains with Postfix Mail Server
I am now hosting multiple domains on DigitalOcean and require a solution for email. Before, I was happy with not setting up a mail server on my droplet and just using Gmail but a new project requires domain specific email addresses. Since my domain registrar points my DNS settings to DigitalOcean, I can’t use their mail services. I need to set this up myself and honestly, going through this postfix tutorial was pretty easy. Below, I will cover how to setup postfix for multiple domains and how to read postfix emails.
