After downloading the trial version of Spam Bully for Outlook Express, I began to experience problems. The program caused my message pane to blank out right after installation. I had to close and reopen Outlook Express to get it to work again. Spam Bully did catch the spam. Unfortunately, it also caught emails I wanted to receive, including an email from my mother.
The way that the interface was set up was confusing. There was a spam folder, which I expected to find. However, there was also an "Unsure" folder which I didn't expect. It took me a while to realize that email I wanted to receive was ending up there.
I finally uninstalled the program. I have never experienced a moment of regret. I do not recommend this program. Don't waste your money.
