Best Self-hosted Email Clients


Table of Contents

Self-hosted email clients are those that we can host on our own server or on our local network. The advantage of using a self-hosted email client is that it makes your email accounts accessible to any devices on a network. We can use these clients to not only integrate third-party email accounts, but also to construct our own email server, which allows us to communicate in perfect privacy over the internet.

If you’re asking why someone would need a self-hosted email client, the answer is simple: accessibility and privacy. If you value privacy, you can set up your own email server. It will give you complete control over your data, and no third-party services will be able to share it with advertising businesses. Second, you may integrate third-party email services with these email clients, allowing them to be accessed via the local network or the Internet.

Best Self-hosted Email Clients

In terms of UX or simplicity of use, the self-hosted email applications I’m going to list in this article are no different from others. Most of them offer an easy-to-use setup so that individuals with little knowledge of email servers can utilise them. However, I recommend broadening your expertise, especially if you intend to host your own email server.

It is not possible to host an email server and then leave it to run on its own; instead, it necessitates ongoing maintenance and security checks. Some of the crucial administrative duties to keep an email server healthy are to update your system, install and configure a firewall, and monitor network traffic.

If you host your email client on your local network, be sure it is secure from intruders. Despite the fact that all email clients are actively being developed, have options to encrypt data, and anyone with access to the login panel will not be able to reach any inbox without proper authentication. Still, I recommend not sharing your wifi password with strangers and keeping your password strong; all of this will help to increase the security of your network.

With that being said, let’s start with the first on the list.

1. Mailpile

Mailpile is an excellent example of an open-source project. Bjarni, Brennan Novak, and Smári McCarthy founded Mailpile in the Netherlands in 2013. All three of these people are experts in their respective fields. Bjarni is a FOSS developer, Brennan Novak is a specialist in user interface design, and Smári McCarthy is an expert in privacy and security. They not only create a privacy-oriented email client, but also one that is secure and has a great user interface that competes with existing proprietary email clients.

Secure & private

Mailpile can easily interface with third-party email services such as Gmail and Outlook, and all emails may be downloaded locally. After downloading, the customer can delete all of their emails from their servers. It enhances privacy and security. If your Gmail account is compromised, the hacker will not be able to access your important emails because they have been erased from the Gmail servers. However, if you reply to those emails from Mailpile, the process of sending a reply will go through Gmail, which means your emails would need to be erased again from their servers after downloading locally.

Not a mail servers

Mailpile is an email client, not a webmail service. Although it is compatible with any email server that supports IMAP/SMTP. So, if you intend to host a mail server, I recommend reading this post, which explains how to use Virtualmin or Webmin to host your own email server. After that, you can use IMAP/SMTP to configure your newly formed mailserver with Mailpile.

How to install Mailpile

Mailpile is available for Linux distributions based on Debian. Install Mailpile by downloading packages or by adding the Mailpile repository. It is suggested to use a repository because it will automatically install available updates.

Install using Mailpile repository

Install required packages –

sudo apt-get update && sudo apt-get install curl apt-transport-https gnupg
curl -s |sudo apt-key add -'
echo "deb release main" |sudo tee /etc/apt/sources.list.d/000-mailpile.list

Get Mailpile without Apache integration –

sudo apt-get update && sudo apt-get install mailpile

With Apache integration –

sudo apt-get update && sudo apt-get install mailpile-apache2

You can go with the second method, i.e. add apache integration so that you can easily open Mailpile on http://localhost/mailpile or http://server-ip/mailpile or

You can use any of the three URLs listed above depending on where you install Mailpile and where you wish to access it.

For instance, I’ve installed Mailpile on my Raspberry Pi, which is connected to the local network. To access Mailpile on any of my home devices, I must first connect my device to the local network and then use the Raspberry Pi device IP address to reach the Mailpile. To ensure that this IP address never changes, I configured my Raspberry Pi’s network settings to use a static IP address.

2. Rainloop

Written in PHP, Rainloop is a web-based email client with modern interface. Rainloop includes practically all of the features found in a modern email client, such as an easy-to-use admin panel, IMAP and SMTP protocol support with SSL and STARTTLS, Sieve scripts, multiple account support, and interaction with prominent social networks such as Facebook and Twitter.

Rainloop also provides customization options to further personalise the user experience. The inbox’s default layout divides it vertically into an email list and a reading section. Users can choose between a horizontal layout and a no split view.

The email client reads emails directly from the mailing server, whereas Mailpile allows users to keep server emails locally to improve privacy.

How to Install Rainloop

Rainloop can be easily installed and configured on any Linux distribution. One can install Apache server and install rainloop just by uploading the files in the apache directory.
