The ImunifyAV extension is now deprecated and no longer available for installation.
Existing ImunifyAV installations will continue operating for three months, and after that will automatically be replaced with the new Imunify extension. We recommend that you manually replace any existing ImunifyAV installations with Imunify at your earliest convenience.

The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.
