This e-mail had for legal reasons to be sent within a certain timescale. Four months later after chasing payment from the client he announced he had sent an e-mail (correct address used) which we have never received. He then forwarded it to my e-mail address which arrived immediately. The e-mail looks suspiciously odd. Part of it has no delivery address bar, another part is totally indented. Due to it being forwarded on to me I can only see where the last message originated from and when. When what I actually need to know is when and if it actually had been sent to the original recipient or not. Is there any way of doing this?
