X-Message-Info and Message-ID?

I have seen following data in the header of hotmail, what are they? I am
wondering if they are hash codes related specific ISP or a computer hardware
infomation from which the email was originally sent out?

Thanks!

X-Message-Info:
LsUYwwHHNt30K9L3krFLO4Llph5BluV/cERX64OoJr8f/TLMjEwToyqQcubJytm/
....
....
Message-ID: <BAY132-F27D788FCE22605EB467783BA4C0@xxxxxx>

All servers assign a Message-ID: line if the client does not. Whether
assigned by a client, or a server, the Message-ID: line is intended to
prevent confusion by servers when handling messages. This is true for both
e-mail, and news.

The X-Message-Info: header line is unique to Hotmail, and probably has some
internal meaning to their administrators. Some clients allow for adding
custom X-Header lines; I can do it with Pegasus Mail for e-mail, and with
40tude Dialog for news. I just did that with this article, but I don't think
you will be able to see it with your news reader:

X-Newsreader: Microsoft CDO for Windows 2000

Which means you read and post using a web browser. Anybody reading this
article using MS Outlook Express, Mozilla Thunderbird, or any other capable
news client, will see the custom X-Header line I created.

In any case, X-Header lines only mean anything in context of the client, or
service which adds them. If you don't manage the server which adds such
lines, or know how/why the service which adds them does so, you will need to
contact the service administrators. None of the Hotmail administrators are
known to read, or post, to these groups.

WLMail, too. Have a look.

Is that to say X-Message-Info line could be nothing to do with the hardware
info. of original PC from which the email was sent?

BTW, can hotmail be easily faked? say, Origianl-Sender-IP, sender-from,
etc., in the hearder?

Thanks a lot!

I'd say not. Despite client software which can add custom "X-Header" lines,
and any attempt to add such lines as are characteristic of specific clients,
or services, the "Received: from * by *" header line stamped by your service
domain gateway (MX) server, and any subsequent internal servers, which are
your trusted mail hosts, will almost always give the game away.

Despite the Hotmail headers, this is not a Hotmail message.

news:1a9xgzckr9b7.dlg@xxxxxx Neither. Just put something in the Keywords: field, and you can then add
whatever you like after that, with each header line preceded by a soft
return. I just tried it out for fun.

except Header, is there any other info. coming with the email that can be
used to track the path of the original sender? I know there are many hotmail
hackers out there stating they can hack the password, is that ture? and I am
receiving spams everyday.

Can you run b64 decoder to check it or point me out how to run it on my own?

Thanks alot!
