Mail Detective helps you decide if that email you got in your inbox is valid or scam by trying to trace the geographic origin of an email. Simply drag an email message from your mail client onto Mail Detective's window or app icon and the app shows you the country and -- if possible -- the city this message was sent from. If your mail client does not support drag and drop of mail messages, you can use the built-in system service or copy and paste raw message source text into the app. Mail clients known to support drag and drop email messages:
  • Airmail
  • Apple Mail
  • Mail Pilot
  • Outlook more...

What's New

Version 1.2:
  • You can now increase the timeout value for querying the GeoIP Web service.


  • OS X 10.9 or later

A whois service can also be found there.

I did purchase a licence for Mail Detective, though, partly b/c its integration with Apple Maps, and not least to support the developers efforts - there's no other, comparable app specifically designed for the Mac.

This app uses Apple maps and only apps installed through the Mac App Store are allowed to access their maps. Therefore, providing a demo version outside of the Mac App Store is not possible -- the demo would not work.


Developers are allowed to provide demo's. I have a number of demo apps and lite versions that can be purchased after a trial. Time to rewrite some of your code if you want sales.

I didn't said that developers are no longer allowed to provide demo versions in general. I said that it is not possible to provide software outside of the Mac App Store that wants to use Apple’s Map Services. If an application wants to use Apple maps, it needs to be distributed through the Mac App Store. Apple does block displaying its maps in apps that are not downloaded from their store.
