Thanks Vasil....
Sorry I should have added earlier -
Is it possible to add the sender address to an existing message header value (type: X-Protective)
Here, sender address will change based on the sender id.
Any suggestion will be of great help.

In general yes, but depends on the header. Some headers will be stripped/overwritten by the server, you cannot for example "forge" and antispam header, etc.
