Global Message Rules

Global Message Rules helps you to filter and manage incoming and outgoing messages before they delivered to users mailbox or sent-out, by applying server based rules that match a specific set of expressions. When a specified rule is matched the associated actions will be executed in the order specified.

> In order to better understand the message flow in the Lumi Mailserver you can refer to Message Flow diagram.
> In short, when a message arrives or sent out from or to your server it will pass through the Routing which will resolve the actual destination of the message and then will be passed to Global Message Rules. Once the message is filtered in Global Message Rules it will be passed to User Message Rules (if the message is not deleted or dropped in Global Message Rules), in which it will be filtered and delivered to User's mailbox (again if the message is not deleted or dropped in User Message Rules).

You can think of Global Message Rules as the virtual-domain-wide rules engine that applies to all users and all incoming and outgoing messages.
The Administrator can create Global Message Rules from the MailServerManager Interface;
MailServer > MailStore > Rules > Message Rules > Global

Create a new Global Message Rule

Click the New button from the toolbar to bring Add/Edit Global Message dialog. Lets look at the fields in this dialog;
Description field: This is a required field where you will give a descriptive name for your new rule.
Match Expression: Our expression (matching expression) for our new rule. Refer to Match Expression for details.
Check button: Clicking this button will check the validation of our Match Expression.
Actions: The type of actions to run when Match Expression is met. Refer to Actions for details.
Enabled: If we uncheck this field our Rule will be simply disabled and checking will be enable.
C heck Next Rule: Dropdown that defines the condition to check the next Rule in Global Message Rules
Always: Always run the next rule once the current rule is finished.
If this Rule Match: Run the next rule only-if this Rule's expression is matched (the result is true)
If this Rule does not Match: Run the next rule only-if this Rules' expression not matched (the result is false

Once you define your new rule click OK to save and return to Global Message Rules pane. Pay attention to Up and Down buttons on the right. This two buttons help us to set the order of our rules, when we have more than one rule defined. When you want to change the order of execution for your rules, instead of removing and re-creating the rules you will simply change its order by using these two buttons. The top-most rule will be the first rule that will run. You can also double-click on any rule to bring the Edit Rule dialog besides clicking Edit button from toolbar. If you see your rule name having a strikethrough that means it is disabled by the admin, Edit the Rule and check Enabled field to enable it back.

In order to utilize the functionality of Global Message Rules, pay special attention to the type of Match Expression and Actions which contains examples and provide inside to available scenarios.
