You can claim to be who you want to while connecting to a mailserver,
but you can't fake the IP from which you are connecting. It is
logged by the mailserver while connecting between two square brackets.
The usual format used in Received: headers is
name (dns-name [ip-address])
"Name" is easy to forge. "Dns-name" is what a reverse lookup on
ip-adress delivers. "Ip-adress" reflects the IP of the machine which
connected to the mailserver which generated this Received: header.
no, this is not theory, this is how email works and things are
Ok, so please show me the evidence of your statement.
