Hi Harold,


The drop event in your message trace result means the email sent to the distribution group was expanded to every recipients in the distribution group and the recipients in the distribution group did receive the email individually.


We have the following article in which some general message trace events are listed, such as RECEIVE, SEND, FAIL, etc.

Run a Message Trace and View Results.


However, some particular events may not be listed in the article. For these kind of events you encounter in future, please let us know and we’ll let you know what they mean.


Best Regards,
