When I visited a proxy-check site accessing through a proxy server, I found that my true IP didn’t appear.
But in the header of the mail that I sent—using Thunderbird—accessing through the same proxy server, there appeared my true IP. Why does this phenomenon occur?
In both Firefox and Thunderbird, I check the item “Use this proxy server for all protocols” just below “HTTP Proxy: foorbar”
Here is what the headers look like; my IP would be in the area where there is now [---.---.--.---]:
Received: from [192.168.0.4] (ISP's URL [---.---.--.---])
by mx.google.com with ESMTPSA id ---------------.0.2015.03.29.--.--.--
for <foobar@gmail.com>
My SMTP server settings on the Thunderbird are:
Port: 465
(Probably I use SMTPS.) and
Connection Security: SSL/TLS
Also, If the IP of the proxy server is something like 99.99.99.99:8080,
then in the SMTP server settings on the Thunderbird, should port number be 8080?
Are you using webmail or an email program? Where in the header is your IP shown? – R-D – 2015-03-29T16:19:12.813
Which king of proxy server do you use? [socks/...] Do you use SMTS (port 465) to send emails? – AnFi – 2015-03-29T16:51:55.640
I edited your question for clarity and context. You don’t go “Thank you for your replies, guys.” because that sounds ridiculous. Just add the info in your question. Also, this site is not a chatroom or message board so you cannot pile question upon question endlessly so I cut out the added questions you placed there since they were too broad and too chatty. The focus of your question is simple: Why is it that I am using a proxye yet my source IP address is showing. – JakeGould – 2015-03-31T17:03:44.010
