imagine if you will....
attempting to verify a provider's services/offerings by contacting her via two distinct email boxes.
now,
imagine that she makes contradictory claims about herself in her response to the two separate requests
but when you write back that you don't believe her because she's contradicted herself, she says she knew both requests were from you - she traced them back to you using her high end pgi box  (what that is, i don't know!) - so she's been playing with your head!
is this a real thing? can a sender (and his computer) be traced down through his dynamic address connected through DSL?
or is she covering her ass with techno-babble?
help???

If it is dynamic you must have sent it on the same session for her to be sure.   It's not really all that "techno" to see this.

In the header of every single normal email address is the IP address that the email originated from.  Unless the email has been spoofed, it is right there, and the path the email took is also there.  Therefore, she (and you) if you can see the header of the email can see what IP Address sent the message.

The only def of the acronynm for PGI I can see is Previosly Given information, which may be a program that scans email messages received and gets all the header info.

Anyways, if you are using any real email program, you can typically see the headers.  They are real interesting in seeing where most of the SPAM originates.

for just that reason - and when i check out the extended headers - by sending email to myself from both email addresses, i find no consistency at all between the various header information!  i thought perhaps there was some OTHER source code (or whatever!LOL) that went along. sounds like she was just playing a hunch....you think?

Doesn't matter if is the same user session or not.  Many ISP's set their IP addresses to expire 30 - 45 days, some as little as 18 or so.  The IP addresses are dynamic to the computer, not the user.  When the addresses renew many times you will keep the same IP address, sometimes you will get a new one.

The PGI box is pure techno-bullshit.  It uses the Flux Capacitor over the FM (Fucking Magic) protocol, and only works on ID-10T emails.  

It doesn't matter what type of email, what domain, or what computer you used to send your two emails.  The header of the email will tell her what email address originally sent the email, but the only IP addresses anyone will see are those of the originating and subsequent servers.  Unless your computer is also your email server, she's as full of it as I am.  Now the government could track you down by an email, but they have subpeona's and swat teams.  Now if you were dumb enough to setup a Hotmail account using your real name and address, well you got other problems.

if you say she was "playing with your head" by bluffing ... weren't you also playing with her head by pretending to be two people?

OK, you guys are contradicting eachother.

Here's the deal guy, if you wrote her from an email address other than ziplip or hushmail (or a few others that hide your IP) then YES she CAN see your ip address!

And it doesn't matter if you waited until you were logged in under a different session to send the second email .. lol

Your dynamic IP address sometimes only changes every few DAYS... NOT every session.

My God....

So YES no she isn't full of shit, she could very well see you wrote from the same IP, which is probably exactly what happened and now she knows you're the same guy.

Simple as that.

You just can't track somebody by reading their email headers, the only IP information there is the server where the email originates from.  If you email from yahoo for example, the IP listed in the header is an email server from yahoo.  Like tripNatl said, unless your home machine is your email server, you can't be tracked.

If you send an email by filling out a form on a website however, you can be tracked, but I don't think that's what we're talking about here.

If you turn off then reboot your cable or DSL modem and then log back on to the network, don't you get a new dynamic IP address?

Sometimes I can't "View Source" for an email when using Outlook.  How can I see the header information in this situation?

thanks.

First, why are you sending her multiple emails to ascertain "services provided?" No saavy provider will provide "details" of illegal sexual activity -for all we know you could be a cop.
Second, what kind of BS is it that you are playing games with a provider who you haven't seen yet -if she's got any brains (and sounds like she has if she recognized 2 emails whether true or not, she won't see you ever.

King -just some friendly advice from a fellow TER person -if you want to see someone, don't get into head game stuff. It's just not cool and not necessary.

Try putting yourself in her shoes for a second.

Ok, here's the deal.  The IP address of any email you send is the IP address of the SERVER that sent the message for you.  We are not living in a peer-to-peer email world.  There are not enough ip addresses for all of the computers connected to the Internet at any given time.  Most ISPs don't even have enough IP addresses to accommodate 100% capacity, or even close to 100% capacity.  The truth is we use creative subnetting, proxy servers, firewalls, NAT, 10. networks, etc. to make it work.  You will never get a lease longer than 24 hours from your ISP unless you pay for a static IP address.  That doesn't mean your address will change every day; it only means you have to renew it every day.  None of that matters though.  
Your IP address and the recipients IP address are not involved in the transaction except in the uploading and downloading of your message from their respective servers, AFTER all relevant transactions have completed and the message is considered sent and delivered. When you send an email, you are only uploading your email to your mailbox on the email server with instructions to transmit it to the desired address.  Your email address and the recipients email address are written in the header.  Your email server doesn't give a rat's ass about anything before the @.  It just moves messages through its MTA to and from the desired .com .org .whatever SMTP server.  This is the point at which your email can be traced, and the point at which any tracing ends.  
But, this is all moot because Singleton makes a very valid point.  This guy deserves to get caught for playing mind games.  Guess I got caught up in the technical aspect of his question and missed the whole slimy head games aspect.

Just because you shut down, power down the DSL modem, then reboot everything and power up the modem doesn't mean you necessarily get a new IP address.  The modem has a MAC address that identifies it to the network it's on - it's pretty easy for the network to ID that MAC address, look it up and re-assign the just released IP address to the same modem.
