Over the years I have become increasingly peed by spam email and have educated myself on sourcing the pests who do this with their many fake schemes and reporting them to their ISP.

 

I have several software options available to me and reading headers etc ( basic search) but one thing I come up against occasionally is loop back address`s, I understand the purpose of these on a network and the industry recognised IP address 127.0.0.1 allocated for loop back for say admin work within the network but thought no direct access is allowed to outside of any given network

 

Is it that a loopback address can be used for hiding email source by commanding any search software to stop at that point? or is it a network issue allowing the loopback to be visible outside of the network when it should not be?

more likely they are using a proxy server

commonly used by Peer 2 peer users to hide their IP from certain government organisations.
