Email Forgery Analysis in Computer Forensics
Emails are usually at the top of the list when it comes to potentially relevant electronically stored information (ESI) sources. They often capture critical business correspondence, agreements, business documents, internal company discussions etc. They are also one of the most frequently forged document types. They can be altered in many ways such as by backdating, changing the sender, recipients or message contents. Fortunately, email servers and client computers often contain various metadata which can be used for forensic email forgery analysis.
One of these metadata fields is the Conversation Index property. I previously wrote about E-mail Conversation Index Analysis and how it can be useful in forensic analysis of e-mails, particularly email forgery analysis. In this post, we will put that weapon to use — along with other computer forensics techniques — and take a close look at a sample fraudulent email message.

Conclusion
As the use of electronic documents as evidence in legal proceedings is becoming more and more popular, so is email forgery, electronic document date forgery and other electronic fraud. However, electronic documents usually contain numerous metadata fields, rendering most forgery attempts discoverable. Email transport headers and other metadata such as the Conversation Index, Sent Time and Delivery Time Microsoft Outlook Messaging API (MAPI) Properties are just a few of the numerous metadata fields computer forensics experts can use during email forgery analysis."
There's some great information in this post (and linked ones) and is perfect for you CSI guys (and those of you in the Legal/ESI/eDiscovery world).
