Exchange 2013 moderation email tracking log

Dear Partner,

We have Exchange 2013 , We got in Mail flow two massages are pending and not received to mailbox user.

Based on Microsoft the about Pending :   If message delivery is pending because a message meets the criteria for an organization-wide rule or policy or because it’s subject to message approval, the status message explains what action a rule is performing or that the message must be approved by a moderator before delivery.

The Owner message sent to user normal email .

We need tracking log if this massage moderation or not ?
