Real IP address of the sender
I have a question about sender IP address that is written in email headers. If we know that this IP is not correct and valid (it means email was sent with using VPN) Is there any method to find out the real IP address of sender from another information in the email header (for example DKIM-Signature or X-UI-Sender-Class or Message-ID or any other information)? Note : the email is sent from mail.com Email server through mout.gmx.com and also have some files attached. Regards
