Dear Members of this Forum
An email transports much more than the ip sender.There are many sites with windows where we paste the copy of the header to know trace the initial IP.But if we want to know a litlle more about the header or the source?
I've tried a web searches:
more information about mail headers
more information about mail sources
But results are poor..
Any proposition for other searches?
I'm not sure I understand your question. An email header is processed and added to by each "hop" that a message takes to get from sender to recipient. There are some customer headers that mail systems might also add, usually beginning with X- and then whatever custom info.
But there's no "hidden" info there. A header says what a header says.
