SquirrelMail  is an Open Source project that provides both a web-based email application and an IMAP proxy server.

The webmail portion of the project was started by Nathan and Luke Ehresman in 1999 and is written in the PHP scripting language. It can be installed on almost all web servers as long as PHP is present and the web server has access to an IMAP and SMTP server.

. 

SquirrelMail webmail outputs valid HTML 4.0 for its presentation, making it compatible with a majority of current web browsers. SquirrelMail webmail uses a plugin architecture to accommodate additional features around the core application, and over 200 plugins are available on the SquirrelMail website

SquirrelMail Configuration : Read: config.php
---------------------------------------------------------
While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others. If you select your IMAP server, this option will
set some pre-defined settings for that server.

Please note that you will still need to go through and make sure
everything is correct. This does not change everything. There are
only a few settings that this will change.

Please select your IMAP server:
 bincimap = Binc IMAP server
 courier = Courier IMAP server
 cyrus = Cyrus IMAP server
 dovecot = Dovecot Secure IMAP server
 exchange = Microsoft Exchange IMAP server
 hmailserver = hMailServer
 macosx = Mac OS X Mailserver
 mercury32 = Mercury/32
 uw = University of Washington's IMAP server
 gmail = IMAP access to Google mail (Gmail) accounts

 quit = Do not change anything
Command >> <-- courier
