MailSlot™ is designed to facilitate the sending and receiving of messages that are digitally signed by the use of the private key (called a PEN, or Personal Endorsement Number) of a digital identity certificate issued by Osmio, the certification authority of the Authenticity Infrastructure.
All Osmio identity certificates are accompanied by an Identity Quality score; MailSlot uses that score in determining how to process incoming messages.
MailSlot provides you with two inboxes – one for digitally signed messages and one for all other mail.
The first inbox is only for mail that’s digitally signed using the PEN of a credential with a minimum Identity Quality (IDQA) score set by you, the mail receiver.
