电子邮件 Webmail
![](/data/attachment/album/202307/17/134939av491mgn4ddzh4c1.jpg)


电子邮件服务将会一直存在，即便去中心化技术会接管互联网。


然而，随着大型科技公司试图控制新兴技术的方方面面，你如何掌控自己的电子邮件服务呢？


无论是企业还是个人，自托管的开源 Web 邮件服务始终是值得考虑的选项。你自己的服务器、你自己的数字基础架构，上面搭上你自己的电子邮件服务平台。这样，你就无需依赖供应商或第三方来管理你的电子邮件服务。你可以按照自己的方式办事。


### 为什么应该自托管电子邮件服务？


![best opensource web based email clients 1](/data/attachment/album/202307/17/135027i5665rrstrr5s58t.png)


自托管一个可用作基于 Web 的电子邮件客户端或与电子邮件应用程序同步的服务，这不是点击一下就完成的过程。


那么，为什么要这么费事呢？难道你不能使用一些诸如 [Proton Mail](https://itsfoss.com/recommends/protonmail) 和 Tutanota 之类的 [注重隐私的最佳电子邮件服务](https://itsfoss.com/secure-private-email-services/) 吗？


当然可以。


但是对于企业来说，自托管 Web 邮件的一些优势包括：


* 用户可以完全掌控电子邮件数据。
* 你可以自己构建符合电子邮件服务要求的基础设施。
* 它为个人、小型企业和企业提供了可扩展性。
* 你可以创建无限数量的电子邮件帐户和邮件别名。
* 用户可以轻松应用高级过滤器和其他保护机制，无需付费订阅。


在这里，我列出了一些你可以选择的最佳选项。


### 1、Roundcube

我想提及几个此类邮件服务项目。

Squirrelmail、Horde 和 Roundcube 仍然是最流行的选项之一，你可以在大多数托管提供商处轻松访问它们。


当然，这些选项并不总是外观时尚或具备像谷歌工作空间甚至 Zoho 那样的功能，但你足够进行基本的电子邮件工作。

OK
Email services are here to stay, even if decentralized tech takes over the internet.

However, with big tech trying to control everything new aspect of emerging technologies, how can you take charge of your email service?

Whether a business/enterprise or an individual, a self-hosted open-source webmail service is always an option worth considering. Your server, your digital infrastructure, and your email service platform. This way, you do not have to rely on a vendor or a third party to manage your email services. You do it your way.

## Why Should You Self-Host an Email Service?

It is **not a one-click process** to self-host a service, which you can use as a web-based email client or sync with an email app.

So, why bother? Can’t you use some of the [best privacy-focused email services](https://itsfoss.com/secure-private-email-services/) like [Proton Mail](https://itsfoss.com/recommends/protonmail) and Tutanota?

Well, yes, you can.

But, for businesses and enterprises, some advantages of self-hosting webmail include:

**The user gets total control over email data.****You get the ability to build your infrastructure that meets the requirements of your email services.****It provides scalability for individuals, small businesses, and enterprises.****You can create unlimited email accounts and email aliases.****Users can easily apply advanced filters and other protection mechanisms without paying for a subscription.**

Here, I list some of the best options that you can pick.

## 1. Roundcube

Roundcube is a popular PHP-based webmail software that provides all the essential features in a simple user interface.

With most of the server hosting providers, you already get it pre-installed. You have to configure it for your domain or create email accounts to get started.

You can also install it and customize it on your server.

## 2. Cypht

Additionally, you can opt for the pro version to get technical support, a priority fix, a personal calendar, a mobile version, and the ability to add multiple IMAP accounts.

## Interesting Mentions

Several open-source projects are under active development that you can experiment with.

Of course, we do not recommend using them for business or personal use. You can try them out to see if you want to contribute to their development in some way.

I would like to mention a couple of such mail service projects.

### Mailpile

While it deserves a spot in the list above, the development for [Mailpile](https://www.mailpile.is) has halted until Python3 rewrite is complete.

It is a fast and modern open-source webmail with encryption and privacy-centric features.

### Cuttlefish

[Cuttlefish](https://cuttlefish.io) is a free and open-source transactional email service. It aims to be an alternative to proprietary services like [SendGrid](https://sendgrid.com).

It is in its early stages of development.

### Pinbox

A self-hosted webmail solution that gets its inspiration from Google Inbox.

[Pinbox](https://github.com/msp301/pinbox) a work in progress and needs a few prerequisites to make it work.

## Wrapping Up

Squirrelmail, Horde, and Roundcube remain of the most popular options that can be easily accessed with most hosting providers.

Of course, these options are not always modern looking or have features like Google Workspace or even Zoho but you get enough to do the necessary emailing.
