Have you ever wondered what happens behind the scenes when you hit that send button? Well, it’s time to demystify the process and learn how to build your own email server like a pro!

So, are you ready to dive into the world of self-hosted email servers? Let’s get started on this exciting adventure together!

Step 1. Signup with a VPS with an open port 25

We will be using Contabo Cloud VPS because it has an open port 25. Port 25 is commonly used for the Simple Mail Transfer Protocol (SMTP). Therefore you need a VPS with an open port 25. Some VPS close this port to prevent spam.

Here are some of the VPS that have an open port 25.

Let’s signup with Contabo VPS!

Contabo New VPS

Choose your term length and region.

Configure Contabo VPS 1

Next choose a storage type. I suggest an NVMe because it is much faster than an ordinary SSD. For the Image, choose Debian or Ubuntu LTS. Be sure it is an LTS (Long Term Support). In this tutorial we will be using Ubuntu 22.04 LTS.

Configure Contabo VPS Storage Type and Image

Generate a secure password and leave Networking and Add-ons as is unless you want to add something.

Configure Contabo VPS Login and Password

Step 2. Install HestiaCP on Ubuntu 22.04 LTS

First, download a free SSH client called Bitvise. We’ll need this software to connect to our server. For Debian users check this HestiaCP installation guide.

Use your server IP address beside the Host and use Port 22. Login as Root using the password we generated during signup.

Login as ROOT Using SSH Client Bitvise

Run the following commands:


If bash doesn’t work, add –force.

Force Install HestiaCP on Ubuntu 22.04 LTS

Follow the following options:

Would you like to continue with the installation? [Y/N]: Choose Y.

Provide an email valid address.

Enter a fully qualified domain. For instance,

You can reboot your server once the installation is done.

Step 3. Access Hestia Control Panel

You can access your HestiaCP through server IP and port 8083: <IPAddress>:8083

Access Hestia Control Panel

Hestia Control Panel Dashboard

Add a non-admin user for security purposes. Just go to Add User to add a new user.

Add an A record for the domain and hostname. Go to Namecheap and add an A record for both non-www and www.

For example:

Our domain is Create two A records with Host value as @ for non-www and WWW for www. You can also add A records for your hostname – cp and www.cp.

  • Type: A record
  • Host: @
  • Value: Your server IP address
  • TTL: Automatic

Namecheap A Records

Next issue an SSL for hostname. Just go to Web > Choose your Hostname > Check Enable SSL

In case you can’t issue an SSL for your hostname in HestiaCP, try the following commands in the command line interface:

v-change-sys-hostname host.domain.tld

host.domain.tld is your hostname.

If you are using RackNerd and you face an error below, go to /etc/hosts, find something like racknerd-071cd7127.0.0.1 and remove it. Then issue SSL using the commands above.

Error: WEB_DOMAINS limit is reached :: upgrade user package
Error: web domain racknerd-095au7127.0.0.1 doesn’t exist

Issue SSL for Hostname HestiaCP

Then access your hostname, instead of IP address.

Access HestiaCP with Hostname

Step 4. Add a domain

Next, we’ll add a domain and issue an SSL. From your HestiaCP dashboard, choose the non-admin user you created. Click Add Web Domain. Check Create DNS zone and Enable mail for this domain.

Add Domain in HestiaCP

Since we have already added an A record for our domain, we can issue an SSL immediately.

Issue an SSL for Domain in HestiaCP

Next, we will add an email account. Go to Mail > Choose the domain > Add Mail Account.

Add Email Account HestiaCP

Now we need to add a PTR record in our VPS. Let’s go back to Contabo. From your Contabo dashboard, go to Reverse DNS Management in the left menu.

Your PTR record should contain your domain both IPV4 and IPV6 to avoid email going to the spam folder.

Step 5. Configure DNS settings in Namecheap

Next, go to your HestiaCP and click DNS > Choose domain and you will have your DNS records. Copy these records to Namecheap. You’ll just need to add A, MX, and TXT records. For a more detailed process watch the video above.

DNS Zone HestiaCP

Now login to Namecheap and choose the domain to Manage > Advanced DNS.

DNS Records in Namecheap from HestiaCP DNS

Once we are done configuring DNS records, we’ll add an A record for our webmail. HestiaCP already has a webmail client. To access it just go to Just replace the domain with your domain.

Go back to Namecheap and add an A record for our webmail.

Create two A records with Host value as webmail and www.webmail.

  • Type: A record
  • Host: webmail and www.webmail
  • Value: Your server IP address
  • TTL: Automatic

Next, we’ll now issue an SSL for our webmail.

Go to Mail > Choose the domain > Edit Mail Domain > Check Enable SSL for this domain

Issue SSL for Mail Domain HestiaCP

After issuing an SSL for the Mail domain, you can now access your webmail securely:

Login using the email account we created earlier.

Step 6. Test Our Email Delivery

Next, we’ll test if we can send an email to Gmail.

Send an Email to Gmail from HestiaCP
Success! We have sent an email to Gmail.

Now, from Gmail, we will reply to that email. Let’s see if we can receive a reply successfully.

Received Email Reply from Gmail
We have successfully received a reply from Gmail.

Step 7. Test Email for Spam

Finally, let’s test our email for spam. If we get a score of 10/10, our deliverability is guaranteed.

We’ll just send a test email to the email address provided by Mail-tester.

Spam Score from Mail-tester HestiaCP

Well, isn’t that sweet to see a 10/10 score? Congratulations, you successfully setup a free email server with HestiaCP, Contabo VPS, and Namecheap!
