+# Status Whisper Mailserver Specification
+> Version: 0.1 (Draft)
+>
+> Authors: Adam Babik <adam@status.im>, Oskar Thorén <oskar@status.im> (alphabetical order)
+
+## Abstract
+
+Status clients are often offline. In order to allow clients to talk to each other while one is offline, we provide offline inboxing.
+
+This current specification is an extension of Whisper v6 and operates under a store-and-forward model.
