SquirrelMail is a lightweight webmail application written in PHP with a focus on simplicity and speed. It provides a minimal interface that works well for legacy deployments or resource-constrained systems. SquirrelMail integrates with standard IMAP and SMTP servers and is easy to deploy in traditional LAMP stacks. It was a practical choice for administrators who preferred a straightforward, no-frills webmail client.
