EmlViewer Pro makes email metadata accessible, including internet transport header information embedded within an email message. This information is often hard or impossible to access in a standard email client.

Email transport header data and properties data is useful for verifying the authenticity of an email message. It can show the server path that the message took on it’s way to the destination inbox.  Note that if the .eml file you are looking at was created locally, there will be no transport header; only emails that have traversed the internet will contain transport header information.

To access transport header details for a .eml file, first open the message in EmlViewer Pro, then go to Mail>Properties.
