Re: Email sent through Tor, Problem

Hello FQ,

These below are NOT the SMTP hops your email followed. These are IP hops, between your PC and the mail server of your friend in China. What is sure is that this information was not retrieved from the email you have sent directly, since no mail client or SMTP server would put the whole traceroute in the mail! Your mail didn't even follow this path, but the following:

- your PC
- lots of IP hops (one TPC connection) to the first Tor node
- lots of IP hops (one TPC connection) to the Tor exit node
- lots of IP hops (one TPC connection) to the Hotmail HTTP server

Till now you had your data sent through HTTP ....
Now comes the SMTP part

- Hotmail HTTP server putting your mail in a database
- I suppose another server sending out you email to the mail server of you friends mailbox (lots of IP hops again)
- your friend "viewing/downloading" the mail through SSH / HTTP / POP3 / IMAP (some IP hops again)

Of all this, in a mail, you have something like the following:

If you have not used Tor, your IP appears in one of the last lines, as it is directly seen at the TCP endpoint of the HTTP server @ hotmail. If you use Tor, but there is some JavaScript sending your IP as data, and this is somehow not filtered, your IP could still appear .... but not the traceroot! So, the question is, what do you mean
by "i have traced the first ip"?

Yeah i am pretty much sure, because i have traced the first ip ie my isp's.
it gives some information like this.

Is there any trick to hide the header information while sending email through hotmail.
Any suggestion?
