Situation: System was upgraded to Plesk for Linux 9.2.1 and tried configuring greylisting. The following error came up:
Failed to exec glmng cli. file does not exist or is not executable: /usr/local/psa/admin/bin/glmng
SpamFilterPropertiesUIPointer->accessItem(string ‘POST’, NULL null)
Basically the file /usr/local/psa/admin/bin/glmng did not exist as it hadn’t been installed properly during upgrade.
Via the command line we manually called: /usr/local/psa/admin/bin/autoinstaller
And proceeded to install the updates that were needing installing. After this had completed, the glmng file existed!
