If i send an anonymous mail or threat mail to someone how they re tracking it...
Tracing an email
wat happens if its from a proxy? can we trace beyond proxy?
yes ! there are some softwares which can track exact URL from where IP is sent.
I am not sure why this is considered "ethical hacking" But yes, there are programs out their that can trace your IP, but if you run a good enough Proxy then you will be fine.
