Can I stop EFA from adding itself to the email header (own name, IP address etc) so that the first thing that appears in the email header is the originating server?

Can you share an example header of what you are seeing (feel free to remove/conceal identifying info)?

(My headers show the originating server as the first thing already after passing through EFA)

This is an example:

I want to remove (or not add):
Received: from mailprotect.oh.local (192.168.1.19) by OH1.oh.local
(192.168.1.17) with Microsoft SMTP Server (TLS) id 14.3.146.0; Tue, 22 Dec
2015 11:14:19 +0000

So the first on the header is:
Received: from bba597144.alshamil.net.ae (bba597144.alshamil.net.ae
[86.98.71.244]) by mailprotect.oh.local (Postfix) with ESMTP id 983FD10069F
for <sipgate@domain.co.uk>; Tue, 22 Dec 2015 11:16:26 +0000 (GMT)

Exchange is adding that header upon receipt, not EFA.
