How To Install or Upgrade

You can view the upgrade process using the command: tail -f /var/log/plesk/panel.log

Important - Manual Action Required
After upgrading to Plesk 18.0.73+ and Warden 5.03 administrators must run the command below to upgrade their Warden dovecot configuration to be compatible with dovecot 2.4 (otherwise dovecot will not start after the Plesk upgrade):

warden --task=antispam:learning:sieve --rebuild=yes --restart=yes

Explaining the Plesk 18.0.73 Upgrade Process

  1. Make sure that you have Warden 5.03 installed.
  2. Upgrade Plesk to Plesk 18.0.73+.
  3. Run the command: warden --task=antispam:learning:sieve --rebuild=yes --restart=yes It will detect that Plesk 18.0.73+ is now installed and rebuild the Warden configuration for dovecot 2.4 then restart dovecot.

Upgrading to Warden 5.03 on an End-Of-Life OS
We understand that some users may be using an unsupported operating system with Warden installed that is end-of-life and may still need to upgrade to fix this issue (CentOS 7.x/CloudLinux 7.x/RedHat Enterprise Linux 7.x/Debian 10.x/Ubuntu 20.04). This can be done using the following commands:

// download the latest verion of Warden
wget https://www.danami.com/clients/downloads/warden.zip

// delete the pre-install checks from the archive
zip -d warden.zip plib/scripts/pre-install.php

// install the extension
plesk bin extension --install warden.zip

// apply the dovecot fix
warden --task=antispam:learning:sieve --rebuild=yes --restart=yes

Just be aware that these end-of-life OS are no longer officially supported by us as they are no longer getting ClamAV signature updates. See here for more information.
