I guess you are not going accept that this is not caching. Ok but here is an interesting one with forwarding messages.Originally Posted by KevinH
I have attached the content of a message here. This seems to be both HTML as well as TXT message. When I forward this message to some one they do not get the forwarded message they simply get my email.
In case you are wondering where the mail came from its the confirmation of an order from Dell.
