How to Set Up Your Own Secure Email Server

Major email service providers such as Google and Microsoft occasionally scan your emails to provide targeted ads and other services. You may be concerned by this as it does violate your privacy. One of the easiest ways to prevent this breach of your privacy is to set up your own secure email server.

Setting up your private email server is fairly easy and once the initial set up is complete, you can further customize it according to your preferences.

What Is a Private Email Secure Server?

Whenever you receive an email, it is first stored on an email server before being downloaded to your email client or browser. These email servers are usually managed by the same companies that provide you with email addresses, such as Google, Yahoo, and Microsoft.

While these services do provide you with a lot of convenience, they can easily scan confidential and regular emails to provide targeted ads and improve services such as Google Assistant. Additionally, government entities and law enforcement agencies can ask your email provider to reveal your inbox.

On the other hand, you have complete control over your emails when you use a private email server. This is because the server is located at your own house, on a computer you own.

The glaring advantage of having your own secure email server is privacy. Your emails are completely your own. You can also use one to send completely anonymous emails.

Your ISP and your employers are completely devoid of any access to your emails. This provides a peace of mind that no third-party email providers can match. A private email server allows you to set up filters that are simply not possible when using a regular email service.

However, all this does come at a cost. You are completely responsible for the security of your email server. While your emails can no longer be snooped upon by companies, the server can still be compromised by a determined hacker.

Email providers have dedicated teams that look for security flaws in their servers. However, in the case of a private email server, you are completely responsible for making sure that the server is secure.

How to Set Up Your Own Secure Email Server

Setting up your private email server shouldn’t be a problem at all, provided you follow the steps listed below accurately.

However, before getting started, ensure that you have all the things needed to set up the server. These include:

• A separate computer with decent hard drive capacity. This will act as the email server and store all your emails.
• A domain name for your private email server.
• A good and stable internet connection.
• An email server service to route your emails. Ideally, it should also have features such as a spam filter, and antivirus protection.

Download and Install an Email Server

The first thing you need to get started is an email server software. There are plenty of programs available. However, most of them are paid.

For this tutorial, let’s make use of an open-source and free email server called hMailServer. To download the application, simply go to hMailServer’s download page and click on the file under “Latest Release”.

3. On the welcome screen, under Getting started, click on Add domain.
4. Under the General tab, type in a domain name under “Domain”. Ensure that the Enabled checkbox is ticked, and then click on Save.
5. Now, using the navigation bar on the left, go to Domains and then click on the domain name you’ve just entered. Click on the Accounts directory.
6. In the Accounts window, click on Add.
