Header Information

[colin]

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?

[shawniverson]

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

Exchange is adding that header upon receipt, not EFA.
