The end is near for SquirrelMail
As you know as a company, we keep our cPanel software right up to date with the latest releases. This allows us to ensure maximum security within cPanel and giving you the latest functionality, it brings.
However, what has been counter intuitive is SquirrelMail, as of the current version of cPanel V76 SquirrelMail is no longer supported or an option. The reason for this and the fact that it will be completely removed from all servers as of version 78 is due to security
cPanel's reason for removal in V78 Onwards
An all too common story with open source projects is a loss of invested developers. A once active, vibrant developer community diminishes as other things take priority. When that happens, its users often leave as well.
SquirrelMail’s last update was 30/05/2013, with their last release on 12/07/2011. In that seven years, 4 versions of PHP have reached End of Life, and we have worked with others in the community to maintain SquirrelMail. Unfortunately, recent security patches have significant problems, forcing us into a choice. Exclude the security fix and ship SquirrelMail with known security flaws, ship a secure version with known interface issues, or attempt to fix the problems.
Webmail users now expect a better experience than SquirrelMail provides. Rather than continuing to ship an unmaintained application, we decided to remove SquirrelMail.
However, in the webmail section you still have the option of Roundcube or Horde after SquirrelMails removal.
