Preventing Local IP Addresses from Appearing in Thunderbird Mail Headers
When using an email client like Thunderbird, it is common to see the IP address of the sender in the email headers. However, if you are using an IMAP server and are concerned about your private IP address (such as your PC's local IP address) being added to the mail headers, this article will provide you with detailed information on how to prevent this from happening in Thunderbird 115.10.1.
Understanding IP Addresses in Email Headers
Email headers contain various pieces of information about an email, including the sender's IP address. This information is used by email servers to route emails and can be useful for troubleshooting and debugging purposes. However, in some cases, you may not want your private IP address to be included in the email headers.
Preventing Local IP Addresses from Appearing in Thunderbird Mail Headers
To prevent Thunderbird from adding your local IP address to the mail headers, you can follow these steps:
- Open Thunderbird and go to the Tools menu.
- Select Options and then click on the Advanced panel.
- Click on the Network & Disk Space tab and then click on the Settings button.
- Under the Connection section, uncheck the box next to "Use IPv6 if available".
- Click OK to save your changes.
By unchecking this option, Thunderbird will no longer use your local IP address when sending emails. Instead, it will use the public IP address assigned to your CPE (Customer Premises Equipment) by your CGNAT (Carrier-Grade NAT) provider.
