Mail Detective tries to determine the geographical origin of email messages in your INBOX via geolocation by parsing the message headers for the sender's IP address, which makes it easier for you to check how plausible the message is. Simply drag the email from your mail program and drop it onto the app’s window - Mail Detective will tell you the country and, if this information is available, the city from which the email was sent.

If your mail program does not support Drag and Drop of messages, you can also copy the email headers and paste it into the app.

Please note that Mail Detective will need internet access to work. If the message is older than 24 hours, the city of origin may be outdated and no longer be correct. In the cases where the sender has used a generic email provider, such as iCloud or Gmail, Mail Detective may not always be able to trace the email back to the sender. In those cases, the location of the webmail service will be displayed.

What's New

Version 1.3

Dragging messages onto the app window now works more reliably.

Mostly locates server farms where mass re-routing occurs. I quess you would say it needs little a more work to be viable.…why yes, yes you would.

I will change my ratings and review given any positive changes to this app.
