Managing Office 365 and Microsoft 365 (Exchange Online) Mail-Flow Rules
The SonicWall Cloud App Security Office 365 and Microsoft 365 Mail-Flow Rules automate actions for emails-in-traffic based on custom policies. In most enterprise environments, every mail-flow rule falls under one of these categories:
- Delivery Rule: A mail-flow rule that modifies the delivery of the email. For example, a Delivery Rule might:
- quarantine emails from a specified domain.
- add emails to the Allowed list that come from a specific IP address.
- mark emails with a specified nickname as Spam (SCL).
- send emails to a specified connector.
- forward emails sent to a specific email address to a different specified email address.
- Modification Rule: A mail-flow rule that modifies the content of the email. For example, a Modification Rule rule might:
- add
[EXTERNAL]
to the subject line of an email message, if the sender of the email is from outside your organization. - add a disclaimer to the email body footer.
- add
The SonicWall Cloud App Security Protect policy for Office 365 and Microsoft 365 for Exchange Online automatically creates a mail-flow rule with the name of “SonicWall - Protect” with default priority of 0 (highest priority).
Unless you have a reason to keep your rules in a specific order, keep the Delivery Rules on top of the Modification Rules. Place the SonicWall Protect Rule between the Delivery Rules and the Modification Rules.
