        Hi,

        Unless you get a complete message header you won't be able to get that info. What you can get is mx records using nslookup. There may be intermediate servers which will be accepting the emails and then relaying it to the mailbox servers. There are firewalls which strip off the message headers and just leave the last exit point of network.

        Give it shot send a message from hotmail id to your internal id and check the complete message header. I know google gives you complete message header.
        Thanks & Regards
