Hi
I have noticed that the internal FQDN/computername shows up as the 'received from' server when I check the headers of an email sent from my Exchange servers.The reason I am investigating this is because I am trying to set up some TLS verification rules between Exchange and a cloud based mail gateway/filtering provider (Forcepoint/Websense). One of the checks is that the certificate common name matches the server which the 3rd party is relaying emails to. This is failing and I can see in the headers the internal FQDN which obviously doesn't match the common name in the cert.
Gmail header looks like this:
Received: from internal.FQDN (192.168.1.5) by internal.FQDN (192.168.1.5) with Microsoft SMTP Server (TLS) id 15.0.1395.4; Thu, 26 Jul 2018 20:39:46 +0100
Received: from internal.FQDN ([fe80::d52a:de6e:91b0:6504]) by internal.FQDN ([fe80::d52a:de6e:91b0:6504%13]) with mapi id 15.00.1395.000; Thu, 26 Jul 2018 20:39:46 +0100
Is there a way i can change the received from address? I have 4 exchange servers (2013) so would need to do this on all of them.
Thanks
