If you get a virus, or rather repeat viruses from a
specific IP, it would be nice to track down who it is
sending it to you.

For example, I get a virus that is To:<me> and From:<my
mom> with sending IP belonging to <someISP>.com.  I know
the sender usually is someone that uses <someISP>.com and
has both me and my Mom in their address book.  I can
deduce who might be the culprit but not always.  

What I would like to do is to scan all email in my inbox
(or PST) and look for the connecting IP in the header
info of all previously received email (or at least the
subnet if they have a dynamic IP).  Chances are the
sender has sent me legitimate email before and I can more
easily identify them to ask them to buy some freaking
anti-virus software (but I digress).  

I cannot seem to be able to get at the header info in any
way other than using View..options.. which is unworkable
way to look.  Any ideas?  I have exported the data to CSV
but Internet header info is not exported.

Mike.
