From CPanelDirect
Squirrelmail is generally not shown if it is not enabled in Tweak Settings of the Web Host Manager. To verify log into your Web Host Manager and select Tweak Settings which is under Server Configuration. The option to look for is SquirrelMail Webmail which must be checked in order for squirrelmail to work.
