 ## DESCRIPTION
+Scenario: [email protected] sends a message to [email protected] and [email protected]. Gmail bifurcates this message into two copies that are both routed to quarantine as phishing in Microsoft. An admin releases both of these messages to [email protected]. The first message that reaches the mailbox is delivered. The second message is identified as duplicate delivery and is skipped. Message are identified as duplicates if they have the same message ID and received time.
