IT Security Stack Exchange is a question and answer site for IT security professionals. It's 100% free, no registration required.

Suppose you have your own domain and send e-mails from there. How and where can you configure to hide your IP address from showing up in the message headers?

Is that something you do at the site you bought the domain from, or at the site your domain is hosted at, or at the e-mail program you are using?

This one isn't really answerable as it stands, and to be honest isn't really in scope for a security professional. There are many questions here on anonymising IP addresses if you must, and you can still find anonymous remailers. – Rory Alsop Jun 15 '12 at 16:07
The question is very specific, so I don't understand why it isn't answerable. Has nothing to do with remailers, because it isn't about anonymity but locational privacy. Privacy is in the scope of security.stackexchange: meta.security.stackexchange.com/questions/810/… And I couldn't find any question addressing those doubts in particular. So can you clarify why it shouldn't be reopened? – Strapakowsky Jun 15 '12 at 16:56
If you read the first section of the FAQ, you will see why it is sort of offtopic. It isn't very relevant for a security professional as you would just configure your mail client or even your PC to use whatever IP address you want. Realistically, if it has your IP address at all it will be an internal address anyway, so of zero value. Can you clarify what your intent is here - that may help us see if there is an on-topic question here. – Rory Alsop Jun 15 '12 at 17:07
Some web e-mail services like GMail hide their users's IP address in the messages. They say that this helps further protect the privacy of their users. My question is simply how you can set up the same protection when using e-mail account of your domain and mail client. I genuinely don't know if it's something to easily config in the mail client (as you argued) or somewhere else, and if always possible to do or if restrictions apply. All that without using proxies, which is possibly what you meant with your PC to use whatever IP address you want. – Strapakowsky Jun 15 '12 at 19:37
Also, experience shows that not only the internal address is normally shown, why would that be so? – Strapakowsky Jun 15 '12 at 19:38
