ISPConfig 3.2.6 Released

What’s new in ISPConfig 3.2.6?

This release fixes several minor bugs that were found in the previous version and implements some new features. Here are a few highlights:


  • Added support for Debian 11.
  • Fixed an issue in the installer where certificate requests for the hostname didn’t work if a self-signed certificate was present.


  • Fixed an issue for sites using chrooted PHP-FPM (which we recommend) that used cached files of other sites.
  • Added function to periodically update all Jailkit jails.


  • Added arc signing for incoming e-mail on Rspamd setups
