Question 1

How do I install Mail-in-a-Box on Ubuntu 22.04?

Accepted Answer

In my setup, I installed Mail-in-a-Box on an Ubuntu 22.04 server by running just a couple of commands from my article and then answering a few simple prompts. You basically confirm, set an admin email, and create the admin password. After a few minutes, the panel is ready and you can log in using the admin email you created.

Question 2

What server specs do I need for Mail-in-a-Box?

Accepted Answer

Mail-in-a-Box is lightweight compared to many other mail server stacks I’ve tested. I mentioned that even 2GB RAM with sufficient storage like 20GB or 40GB is more than enough to run it smoothly. For most beginners and small setups, that’s a very comfortable starting point.

Question 3

Do I need to manually configure SPF, DKIM, and DMARC for Mail-in-a-Box?

Accepted Answer

That’s the best part—unlike Postal, iRedMail, Mailcow, etc., I didn’t manually add all those DNS records. I only updated the domain nameservers to the custom ns1.box and ns2.box pointing to my server IP. Mail-in-a-Box automatically configured the important DNS records required for inbox delivery.

Question 4

How do I set custom nameservers for Mail-in-a-Box on Namecheap?

Accepted Answer

I went to Namecheap’s Advanced DNS, created custom nameservers like ns1.box and ns2.box, and assigned the same server IP to both. Then I went to the domain settings and selected Custom DNS and pasted those two nameservers. Propagation can show “up to 48 hours,” but usually it starts working much faster while you’re installing.

Question 5

How do I access the Mail-in-a-Box admin panel after installation?

Accepted Answer

After the script finishes, it gives you a URL—just copy it and open it in your browser. I logged in using the admin email I created during installation (like admin@yourdomain) and the same password I set in the prompts. From there you can check system status, DNS propagation, and manage users.

Question 6

How do I enable SSL/TLS in Mail-in-a-Box?

Accepted Answer

Inside the admin dashboard, I went to the TLS/SSL certificates section and clicked to provision SSL. It applies from the panel itself, so you don’t have to do complicated manual certificate steps. This is important because secure mail submission and trust are key for deliverability.

Question 7

Which SMTP port should I use with Mail-in-a-Box for sending emails?

Accepted Answer

I used port 587 because it’s the secure submission port and works well with authentication. In my test, I used the hostname as the SMTP server, enabled secure connection, and authenticated with the mailbox username and password. This is the clean and standard way to connect most apps/tools.

Question 8

Why does my SMTP testing tool show errors even if my setup is correct?

Accepted Answer

I’ve seen this multiple times recently—sometimes the testing tool itself creates problems and shows misleading errors. In my video, one tool was acting weird, but when I tested with another SMTP tester it worked perfectly. So if you’re confident you followed the steps, always confirm using a second tester before changing your configuration.
