This file contains data used by the WC24 mail engine. The following list is the mail engine URLs contained in this file. Like most other WC24 URLs, you need the internal KD SSL client certificate to access the servers.
All URLs, except account.cgi, are now defunct as of 2013.
- https://amw.wc24.wii.com/cgi-bin/account.cgi - This generates a password and mlchkid, for usage when contacting the Wii Mail scripts for authentication
- http://rcw.wc24.wii.com/cgi-bin/check.cgi - This is where the Wii checks if it has any mail; this has a challenge as it's over HTTP.
- https://mtw.wc24.wii.com/cgi-bin/receive.cgi - This handles receiving of Mail.
- https://mtw.wc24.wii.com/cgi-bin/delete.cgi - Once mail is received, the Wii contacts this script to delete the mail from the server database.
