What
is SquirrelMail?
SquirrelMail is a standards-based webmail package
written in PHP. It includes built-in pure PHP support for
the IMAP and SMTP protocols, and all pages render in pure
HTML 4.0 (with no JavaScript required) for maximum compatibility
across browsers. It has very few requirements and is very
easy to configure and install. SquirrelMail has all the functionality
you would want from an email client, including strong MIME
support, address books, and folder manipulation.
Project origins
The need arose in our organization for the access
of email and address books from anywhere in the world. Obviously
a web interface is ideal for this, given that the user has
access to the Internet. After reviewing several open source
projects we realized that we were going to need to do some
fairly major customizations to get things to be a nice fit
for our needs. So the decision was made to create our own
for some of these reasons, and for fun (we really like PHP).
We decided to open source the project to contribute to the
community that has contributed so much to us.

Stability
SquirrelMail is stable enough to use in a production
system. It is, in fact, already used in several production
systems around the world, handling thousands of users per
system. There might be some bugs - no project is perfect -
but they are most likely minimal. We test pretty thoroughly
before releasing a version marked as "stable".

License
SquirrelMail is licensed under the GNU General Public
License (GPL), so there are no license fees to worry about.
Support
There are two different types of user categories
with different needs when it comes to support.
If you're using SquirrelMail to read and write mails, but
someone else manages the SquirrelMail installation you're
using, you're an end user. SquirrelMail is typically installed
for end users by their employer, the school they attend, some
organization that the end user is a member of, a hosting company,
or an Internet service provider (ISP).
