Configuring and Customizing SquirrelMail

Well , the time has come for our webmail. Squirrelmail is really cool, though there is other competitors such as RoundCubeMail.

The Squirrel lets you use many plugins, making it more robust. In addition, of course, it is compatible with MySQL and LDAP.

If you have not installed it, run the command:
# yum install squirrelmail –y
