Sometimes, IMSVA quarantines certain email messages unexpectedly because a blank expression in these email messages has been deleted by mistake.
To fix this, the trimming mechanism has to be disabled:
- Open the imss.ini file in the "/opt/trend/imss/config" folder using a text editor.
- Add the following setting under the [general] section and set its value to "no".
[general] EnableTrimSpaceExpression=no
The default value of this key is "yes" which enables the mechanism. - Save the changes and close the file.
- Restart scanner service using the following command:
/opt/trend/imss/script/S99IMSS restart
