"Welcome to SpamSieve" + dialogs every time I launch mail?

Hi all.

I’m getting the splash screen, statistics dialog, and the Help page every time I start Mail. This is only happening on one system. Anybody have this problem and a solution?

Thanks!

This means that SpamSieve’s corpus does not contain both spam messages and good messages. So either you need to follow the setup instructions in the Help page that it opened, or else there’s a disk or permissions problem such that SpamSieve is unable to save the corpus. In that case, there would be some error messages in the All Messages section of the Console application.

Never mind.
I found the other threads about it. Training one message as “good” eliminated the problem.
