sending unsolicited email is a violation of most ISPs (internet Service Provider) Terms of Service (TOS). I don't know about outlook or other email programs but with YAHOO! go to options then general preferences and select full headers on all emails. As an example here is a copy of a TDR email

Most of the information in the headers is not worth looking at but 2 lines.
One is the "Originating IP" and the other is the "To:" line.
If your email is not in the "To" line then the email is spam.
As I said before, SPAM is against most ISP TOS. The only line in the header that tells the absolute t ruth as all other info can be fakes is the Originating IP. Copy this and go to
Broad Band Reports and paste the IP. You may need to go to another page to get actual results but it is well worth the time spent. When you get the information look for the -- email address removed -- or .com and forward the email to that address with the full header. If you don't send the full header there is nothing the ISP can do.
EDIT:
In the return path if there is a web based email provider there send it to -- email address removed -- also.
Also send all spam/scams to -- email address removed --
