How to Create a Mailbox Rule That Matches Every Inbound Message

You can create a mailbox rule that matches every inbound message that another mailbox rule does not filter.

To create this type of rule, set the filter as Subject Contains and the filter string as a period and an asterisk (".*").

• A period matches any character except the line break.
• An asterisk matches zero or more occurrences of the symbol immediately before it.

As a result, this combination matches zero or more characters that are not line breaks.

Example: A "Catch-All" Mailbox Rule

This example demonstrates how you can use a ".*" combination to match every inbound message:

Filter = "Subject contains"
Filter String = ".*"
