SquirrelMail

Is SquirrelMail actively maintained?

We cannot measure this one. SquirrelMail is developed outside the platforms our data source collects activity from, and its repository lives at sourceforge.net — so there is no commit history or release cadence here to score.

Read that as missing data, not as a warning. Several of the best-maintained projects in this catalogue are unrated for exactly this reason. To judge it, open the repository and look at the date of the most recent commit yourself.

What SquirrelMail actually does

SquirrelMail is a browser-based IMAP client written in PHP, functioning as a webmail interface for accessing mail servers. It allows users to read, send, and organise emails directly through a web browser rather than a dedicated desktop or mobile application.

Best fit: It suits administrators seeking a lightweight, traditional webmail interface running on standard PHP infrastructure.

Worth knowing: The project lacks recent tagged releases and active commits, meaning you may encounter unpatched vulnerabilities or compatibility issues with modern PHP versions.

Deployment notes

As a PHP application, it typically requires a compatible web server such as Nginx or Apache, along with a PHP runtime environment and a connection to your existing IMAP mail server.
