Re: Finding out who owns particular IP addresses

Have you examined the attachment type?  It would be easy enough to deliver
the message
w/attachment directly to your MTA while entering invalid headers.  Might
make for a decent worm.

Your headers should still show the source host as this is not generally an
option specified by the client.

Take a look at your attachment, lets see if it contains a trojan/backdoor
app.

I think all Emails have headers to some point


Are you using Outlook or something?

it might hide some header info

if u are in outlook express you can right click on a email and go to
properties
there is a details tab that should show you what server sent you the
email

if u are in outlook

open a email then go to view options
in the main window you should see the header and the server it came from

Even if you change a email to a fake from address
it should still show you what server delievered the email

sendmail will probably have a log of what server connected to it
But I'm still learning the joys of send mail
