Version 76 of cPanel has just been installed across all of our servers and will be the final version of cPanel to include SquirrelMail, the oldest of the three Webmail applications we currently offer to our customers.
SquirrelMail will be fully removed in version 78 of cPanel, which is expected to be released within the next few months.
SquirrelMail has unfortunately been abandoned by its original developers and has not seen an update since 2013. cPanel has been patching SquirrelMail’s code with security fixes ever since, however this task has become too large for cPanel to continue to maintain.
As better alternatives exist, SquirrelMail will be removed in the coming months and only our RoundCube and Horde Webmail applications will be offered to our customers going forward.
If you currently use SquirrelMail, we recommend switching to RoundCube (our personal favourite) or Horde the next time you log into Webmail.
If you have any questions or concerns, please feel free to contact our Support department for assistance.
UPDATE (Apr 8, 2019): With the release of version 78 of cPanel, SquirrelMail has now been removed from all of our servers.
