Re: OT: IP of the originating machine from a gmail email

I've always wanted to get around to testing this with Gmail, but I've seen 
Hotmail and Yahoo leak the originating IP in the past (not sure if it still 
does). Here's my testing:

1) Send an email from your gmail account to some other account you control. Use 
the web interface when composing the email. Check the headers when you get it. 
I don't expect this to show anything except Gmail's server IP.

2) Send an email from your gmail account to some other account you control. Use 
a fat email client (Outlook, Eudora...) to compose the message and connect to 
Gmail to send it. With other services, this sometimes leaks the IP of the 
sender in the header info.


Or ask Google if you have a legal reason.

You could also be a bit more active. Reply to the Gmail account you want to 
probe, but include an embedded image hosted on some remote server. When the 
mail message is viewed, most people should still auto-load images and you'll 
see the originating IP in your logs. This is not foolproof; you need a web 
server, need them to check from an identifying location, need them to view 
images, and so on. This should work better if you Google the email address and 
try to appeal to the interests of the user based on the resulting research...

Hello,

I was wondering if there is a way to get the IP address of the machine
that was used to compose an email that was sent using gmail?
