How get article ID after sending to NNTP server Indy 8

Using Indy 8, after I send a news article to the server:

idNNTP1.send(idMessage1);

is it possible to get the server to return the article ID that was created
as a result of this, and if so, how?  I thought it might be a property of
idNNTP, but can't find it anywhere.

Thanks !!
