I have sent the email from my email account x@gmail.com to y@gmail.com or y has sent email from his account y@gmail.com to my account x@gmail.com. Now my question is, by any way to some other person say z (totally unrelated to x and y in all the way) to know that x@gmail.com has sent the message to y@gmail.com and vice versa, provided z knows the email ids x@gmail.com and y@gmail.com
thanks
