I have used SpamSieve for a long time, but for a variety of reasons, I want to quit and go back to the junk filter on Mac Mail. Unfortunately, I'm having trouble doing that. I deleted the SpamSieve material in the Application Support folder under Library under my user name and deleted the SpamSieve "rule" within the Preferences section of Mail Mail. But every time I open Mac Mail, SpamSieve also opens and I get introductory stuff on how to start testing my SpamSieve filtering.
I'm sure I'm doing something wrong, but I don't know what.
