I've been usig SpamSieve for months (with the latest version of Apple's Mail), and when it doesn't catch a spam message and places it in my Inbox, then I just highlight the message and choose "Train as Spam", which causes it to be automatically moved to my Spam folder (where all junk mail goes).
BUt a couple of days ago, this process stopped working. When I see a spam message that's gotten into my Inbox, I try to "Train as Spam" it, but instead of moving the email to my Spam folder, it simply gives the email a grey color, and leaves it in my Inbox.
Any idea why, and how to fix?
P.S. You can see a screen shot here. Note all the spam messages in grey. Normally, they move to the Spam folder, but have stopped doing that.
