Sorry because I know it's a off-topic, but saw several comments in this
list about this issue when receiving spam and I got no answer from two
newsgroups issuing this question.
What I'd like to know is how to find out the outgoing pop server of
every e-mail reading "Received:" headers.
I tried several times with 'nslookup' and 'whois', but almost always, I
receive a response from whois or nslookup like:
No match for domain XXX.YYY.WWW.ZZZ
I issued as command:
$ nslookup XXX.YYY.WWW.ZZZ
or: $ nslookup pop-host.domain.com
or: $ whois @...etc...
but many times with same results.
How can I use the headers to know the real origin of e-mails?
Which is the proper command? Finger, nslookup, whois, traceroute...
etc..
Or how can I combine them?
What should I use: de domain in IP[XXX.YYY.WWW.ZZZ] format or as
nameserver?
TIA and sorry again!
