I used to use 3rd-party mail services like Gmail or Outlook for a long time.
Recently, I deployed some websites and I needed to send emails by my own domains.
This is really complicated with Gmail, of course they let us do it.
Then I thought I need to host mail-server myself.
I found some solutions like docker-mailserver, mailcow: dockerized, mailinabox..
Most of them are combine of Postfix, Dovecot..
But I wanted something new, easier to understand and maintain then I found Stalwart.
The docs is useful but it’s not very clear for beginner like me. I have been struggling to understand how Mail Authentication works.
But I made it works.
I’m using it for 2 domains. Local domains via local SMTP, external domains via Mailjet Relay. It works perfectly.
I’ll pay for other Mailjet Plans when I need to send more emails.
Thank to Mailjet, they have Free Plan for now.
