Question Trouble with "ExecuteSpamtrain"

[Crey]

Server operating system version

CentOS Linux release 7.9.2009 (Core)

Plesk version and microupdate number

18.0.46.2 Plesk Obsidian 18.0

When we do steps from this manual https://support.plesk.com/hc/en-us/articles/115003117405-How-to-train-SpamAssassin-on-Plesk-server- we dont see any files into "Using the sa-learn utility (For Plesk on Linux)" on step 4. "Copy the generated files from the step №3 from /root/.spamassassin/ to the .spamassassin folder of the required mailbox, for the example [email protected]:" we dont see any new files into /root/.spamassasin, this is normal? And as we see, ExecuteSpamtrain not working on 3 different plesk Obsidian, how too see logs after "ExecuteSpamtrain" function, and how to make it work correctly?
