Features

・View delivery route
・When there is a possibility of garbled characters, adjustments are made to display as much as possible

Validity of information

・The countries and addresses shown in the route are not highly reliable.
・Since Received headers can be forged, the delivery route and send time information may display tampered data.
Also, since route information is based on current DNS data, it may become unavailable, change, or lose accuracy over time.
・Automatic language and character encoding detection is based on estimation, so the results may differ from actual values.

Known issues

・The parsing of Received headers is not very accurate.
・The center coordinates of the route map may extend beyond the display area as they are not calculated taking the spherical shape of the Earth into account.
