Connecting Axigen to Trellix DLP Prevent

Hello Everyone,
Can anyone please help me with connection Axigen mail server to Trellix DLP prevent server.
There is a older discussion about this on the forum (Connect Axigen with McAfee DLP Prevent), however i do not think the configuration presented there is valid anymore as i have created the configuration as instructed and Axigen server still doesn’t foreword any email to the DLP server.

Thanks
