8.5 hours into my spam experiment, here are the results so far:
87 in the spam folder, all correctly identified 37 in the unsure folder (3 incorrect) 15 that I had to manually remove from the inbox--I'll mark them as spam later. For now they are stored in a temp folder.
Most impressive, it is removing those annoying messages with the strange characters in the from: field that set off my neurological symptoms when my computer reads them aloud! Yes!!! SpamBrave is a winner!
