Hi Jeremy
Thank's for your answer.
The smtp transport to this specific Exchange server does not work with chunking enabled. With chunking disabled resp. DATA it works.
I don’t have any access to the log of this exchange. Maybe I can ask for it.
Exim is version 4.89 #0 (FreeBSD 11.0) built 11-Mar-2017 21:16:46
