Horde was a popular webmail platform for a long time! However, it’s going to be depreciated at the end of November.
After many years of satisfactory performance Horde Webmail will be shut down. Unfortunately, this is necessary for security purposes, Horde has not been updated in more than five years and relies upon an outdated version of PHP, 7.4, that is prone to infiltration.
The end of Horde Webmail
PHP 7.4 reaches end-of-life on November 28th, 2022. Each release branch of PHP gets support for two years from its initial stable release. During that period, bugs and security issues are fixed and released in regular point releases.
Once a branch reaches the End of Life, no further support is provided, This includes updates for critical security issues.
Thus using an End of Life PHP means there may be known bugs at the PHP level that will never be fixed and may leave your site vulnerable.
NB: Once deprecated, all data currently in Horde, such as contact lists or calendars, will be automatically converted and imported into the Roundcube Webmail client. This is automatic, so, no action is necessary on your part!
Final
Thoughts
At the end of the month, Horde Webmail will be shut down. Don’t worry though! All data in Horde, such as contacts, calendars, emails etc will automatically be imported into RoundCube webmail.
