I use some additional signatures, but some legitimate email is being flagged as a virus. From my research you can whitelist a signature so it does not scan an email against it. I am wondering two things, did I create my whitelist file(s) in the wrong folder and/or did I not put the whitelist files in the correct folder:

Running version: Build 7957 (Oct 14, 2021) 

Put the whitelist files: C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\share\clamav
File 1: sigwhitelist.ign2
File 2: whitelist.ign2

Both files contain the same signature names:
Dummy.Whitelist.Signature
