Looks to me as though there may be a firewall-type device on your
perimeter which is doing more than simply NAT. The origin_ip is
typically the address of the sending host, which would be public. This
holds true even when QMT is behind a NAT'ing firewall (I typically do this).
Is outlook.com the only domain you have messages coming from which show
this 10. address?
Is there some sort of VPN going on here?
What device is sitting on the immediate outside of QMT?
