Why? They could be on a VPN, spoofing or something else. Just add them to your spam blocker and leave it at that.
There are too long discussions about spoofing, bouncing and more about email that we would be back to research and rehashing all this. If you want to dive into forensic email tracing, you have a lot to research now. But what I'm seeing is few if any will join you on this quest as it's an old quest.
I am trying to identify the source of a persistent spammer to my Hotmail account. I want to paste the message source information here to clear up a few questions I have regarding it. Is this NOT a good idea since it will make my IP number public....? -
Also regarding the message source info, before I paste it, the last IP number registered (i.e. first in the message itself) is not the same as my own IP number - how can this be so.
Additionally I have identified the IP of the spammer from the message source info - how do I go about reporting this to the relevant ISP to have the spammer removed from their service.
Lastly, in a different spam message the last IP (the one which I believe should be mine given it is the same listed last in all my other emails - though why it doesn't appear to be the correct one is a question I have already asked) is, for whatever reason, not the IP address which appears to be my own, but a different one - mine appears second to last. Is there a possibility someone has managed to highjack or mimick my IP and server so that I appear to be the source of spam to unwitting other email account users and also how could they then make sure that some other IP address is listed as the last recipient of the email, and thus the one anyone who checked the message source would be the apparent certifiable IP address.
Thanks in advance for any answers
