USAFRet :
This depends a whole lot on what email system you use. Generally, at most you can get the IP address, which may identify the sending ISP. Maybe.
As far as what make of PC? No.
Thanks USAFRret, that's how I understood it to be. I can trace the IP which gives me a known SP in some instances and "private" in others. I just wondered if there was any other encrypted information that would help me pinpoint the source.
Is it safe to assume then I cannot obtain the physical address, let alone a specific computer?
Thanks again.
