Since cPanel first introduced webmail to its users over ten years ago SquirrelMail has been bundled as one of the default available webmail applications. Unfortunately SquirrelMail has fallen far behind the times, as it has not seen an update since 2013 and has not had an official release since 2011. Due to the fact that the application is no longer maintained cPanel can no longer justify bundling it with future updates. Squirrelmail support will be deprecated as of cPanel/WHM version 74, and it is expected to be removed completely by version 78.
