IMAP4rev1 endpoint
Module 'imap' is a listener that implements IMAP4rev1 protocol and provides access to local messages storage specified by 'storage' directive.
In most cases, local storage modules will auto-create accounts when they are accessed via IMAP. This relies on authentication provider used by IMAP endpoint to provide what essentially is access control. There is a caveat, however: this auto-creation will not happen when delivering incoming messages via SMTP as there is no authentication to confirm that this account should indeed be created.
