What happens with rules in the mail?

Question

My rules are not working correctly....What happens?

Answer 1

in mail, you can set it to do certain things if it meets the criteria
The first rule, which comes preset makes any emails from apple appear slightly blue in your list, you can disable this with the checkbox or just Remove it altogether.
Add Rule settings
Use the Add Rule pane to create the conditions a message must meet for the rule to apply and the actions to take when the rule is applied.
Option
Description
Description
Enter a description of the rule, which appears in the list of rules. For example, “book club.”
If “any” or “all” of the following conditions are met
Specify when the rule applies to a message by choosing “any” or “all” from the pop-up menu. The rule can be applied when a message meets any (even just one) of the listed conditions, or only when it meets all of the conditions.
Conditions list
Using the pop-up menus and the text field, create one or more conditions.
For example, choose Subject from the first pop-up menu, choose Contains from the second pop-up menu, and type “book club” in the text field. Click Add to create another condition, or Remove to delete one.
To add message headers to the pop-up menu, choose Edit Header List from the pop-up menu, click Add (+), enter a header name, and then click OK.
Actions list
Using the pop-up menus, specify actions to take when a message meets the required conditions.
For example, choose Move Message from the first pop-up menu and then choose a mailbox named “my book club” from the second pop-up menu. Click Add to specify another action or Remove to delete one.
If you have multiple rules, it’s recommended that you create an action using “Stop Evaluating Mail Rules.”
As for rules not working, make sure everything is correctly set
