Are you able to post a screen cap or the content of the NDR?

did you tried reconfiguring the user account In the device?

Is this happening for an email he sends or he gets the bunce back for any email he sends to anyone from his iPhone?

try to check the message trace from EAC for the detailed information regarding that email.

You may also share the bounce back for further analysis which he is getting.
