Multiple Domains on mailcow With One IP Address Mail Server to Send/Receive Emails

In this tutorial, I will be showing you how to add multiple domains on mailcow without using another IP. This method works on multiple domains with one mail server running on mailcow.

I will show you how I mapped DNS for the new domain. Send and receive emails on different email domains. Just rinse and repeat the process.

You MUST have a VPS with open port 25 to send emails.

Whats the benefit to send with multiple domains i think its should be add multiple ips to one mailcow

Thank you for the content. Subscribed!
One question.
Can I host using mailcow or fastpanel to send and receive email using contabo or any vps server with cloudflare.
But i want to have a endpoint to send email with my application, like my golang application sending emails ?
Thanks

It didn't work for me my friend...
I have 3 domains, 2 of them can send and receive and the last one can just send but not receive...
5 days trying to find what is happening, but still nothing, is frustrating !
