Why Some Individuals Choose to Run Their Own Mail Servers for Personal Email

In the realm of digital communication, owning and running one's own mail server can provide a level of control, security, and cost-effectiveness that many individuals find compelling. This article explores the reasons behind this choice and details how to set up an SMTP relay using sSMTP, a lightweight method for relaying email messages.

Control and Privacy

One of the primary reasons why some individuals run their own mail servers is for greater control over their personal communications. Unlike relying on third-party email services, running your own server allows you to maintain full control over your email infrastructure. This includes the ability to manage your domain name, configure email policies, and ensure that your emails are not subject to the data handling practices of external providers.

Cost-Effectiveness

The cost of using third-party email services can escalate significantly, especially for those with large mailing lists. For example, services such as AWeber or GetResponse can become prohibitively expensive for large-scale email campaigns, making your own self-hosted solution a more financial viable option. While the initial setup cost for running your own mail server might be higher, the long-term savings can be substantial, especially when you consider the potential for scaling and automation.

Security and Reliability

Relying on your own mail server can also enhance the security and reliability of your personal communications. Here’s a step-by-step guide to setting up an SMTP relay using sSMTP, a simple yet effective tool for relaying email messages:

System Preparation

Before you begin, ensure that your system is up to date and has the necessary dependencies installed. Use the following command to install sSMTP on your system:

apt install ssmtp

Then, open the configuration file using your preferred text editor:

vi

Here’s what a typical configuration might look like:

rootjoe@

mailhub

AuthUserjoe@

AuthPassapp-specific-password-from-Google

Add or change app password

Docs

UseTLSYES

UseSTARTTLSYES

rewriteDomain

hostname

File Permissions

Next, secure your configuration files with the appropriate permissions to ensure that only the root user can read and write to them:

ll /etc/ssmtp/

The output should resemble the following:

-rw-r----- 1 root mail 279 Aug 20 21:10 revaliases

-rw-r----- 1 root mail 848 Aug 20 19:04

Conclusion

While running a full-fledged sendmail installation on a personal machine might not be necessary for most individuals, the benefits of using a lightweight solution like sSMTP can be significant. By providing better control, cost-efficiency, and enhanced security, running your own mail server can be an excellent choice for those looking to enhance their digital communications.
