MailSpy is an application that can you show the geographic location from where emails you've received have been sent. MailSpy shows the sender location as well as the location of intermediate 'stops' the email has taken on its way to you, as well as additional information like the email client the sender has used. Note that only emails sent from email-clients or apps on mobile phones can be analyzed, as most emails sent from 'webmail' services do not contain the necessary information.
