Plesk 9.2.1 greylisting not working

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

0: GreyListManager.php:1099
GreyListManager->_exec(string ‘enable-checking’)
1: GreyListManager.php:87
2: SpamFilterPropertiesUIPointer.php:23
SpamFilterPropertiesUIPointer->accessItem(string ‘POST’, NULL null)
3: UIPointer.php:596
UIPointer->access(string ‘POST’)
4: plesk.php:38

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!
