I'm drowning in spam (about 500/day) so I'm trying to use content filtering to get rid of some of it. I have a pair of rules. The first rule looks at the from address, and if it's in a wildcarded list, then prefix the subject with SPAM-ADDRESS:. That rule is working. The second rule looks at the subject, and if it contains SPAM-ADDRESS:, marks the email as read and moves it to Deleted Items.
They are not in a single rule because other rules need to execute between the 2 steps, to prevent email from trusted senders from being thrown away.
The second rule does not work. Why?
