The config error is not surprising, you turned off the code that interprets
"blacklist_subject".

If you re-enable the WhiteListSubject plugin and remove that blacklist_subject
entry from your database, does SA stop misclassifying messages?

"positive message" = SA scored it as Spam
"negative message" = SA scored it as Ham

"true positive" = SA correctly classified it as Spam.
"false positive" = SA incorrectly classified it as Spam, it's actually Ham.


Thanks for posting your blacklist_subject lines. I think now that's all we need
to reproduce the problem, but you are welcome to attach the headers from a
misclassified ham message so that we have more evidence to examine.

The Perl version change may indeed have broken the WhiteListSubject plugin with
respect to non-ASCII target text. You will probably have to disable that
blacklist entry until it can be fixed.
