We have tested the stopword list in EDM. Even if the default stopword list is used, the EDM policy still detects stop words in messages.
Release : 15.7
Component :
The stop words file is not being found by the default relative path of ../config/stopwords in indexer.properties
Modify the indexer.properties file located at C:\Program Files\Symantec\DataLossPrevention\EnforceServer\15.8.00000\Protect\config
To reflect the full path of your stop words file
AKA:
Change it from ../config/stopwords to <drive letter>:/Program Files/Symantec/DataLossPrevention/EnforceServer/15.8.00000/Protect/config/stopwords
