Removing / Masking Recieved From header

[SigmaX]

I administrate sites of an adult nature, and in supporting our customers neither I nor the folks I work with are overly keen on having our personal IP addresses included in all outgoing emails. I did some research and tried removing that header by editing the /etc/exim.conf file, but that didn't work, WHM doesn't even show my changes when I view the config in the advanced editor. How can I ensure a certain level of privacy for emails sent via smtp?

Thank you!

Info on our setup:

CENTOS 5.9 x86_64 standard
WHM 11.36.1 (build 6)
Exim version 4.80 #2 built 20-Mar-2013 13:37:18

Hello

It's ultimately the email client that is adding the sender's IP address to the message header. For example, you will notice the same behavior when using Horde and SquirrelMail, however Roundcube will not display the sender's IP address in the message header. The workaround to this is to have the customer use Roundcube, or search out an email client that will not add their IP address to the message header.

Thank you.

Interesting...I tried this: How to hide your private IP in Mozilla Thunderbird | How to hide your ip and while thunderbird is sending the domain I set to the server, the headers still include my personal IP address, just now my custom helo argument is appended to it. Any thoughts?

Yes, that guide only lists how to change the "hello_argument" in the Thunderbird email client. It's important to keep in mind that a client must send it's own Domain in the Helo/EHLO command per RFC requirements. If you remove this information completely, most mail servers will mark the messages as SPAM. You may need to consider using a VPN for email purposes to avoid revealing the source of the emails.

Thank you.
