[imp] RFC 822 - Security hole???

[G G Papazoglou]

Hi. I use IMP with a mail server on a different machine.
I have sent a mail using a dial-up connection. So, when I examined the
RFC-822 header generated, I was surprised to see that the whole course
of the message is recorded! It shows the initial IP of the dial-up
connection (which of course could be a static IP), then the IP of the
mail server, and then the IP of the server hosting IMP...This is
really unwanted behavior. Can I prevent this from happening?

See what exactly this header is:
