mod_roster_command: Fix subscription when the "user JID" is a bare domain. Do not attempt to update the roster when the user is bare domain (e.g. a component), since they don't have rosters and the attempt results in an error: $ prosodyctl mod_roster_command subscribe proxy.example.com contact@example.com xxxxxxxxxxFailed to execute command: Error: /usr/lib/prosody/core/rostermanager.lua:104: attempt to concatenate local 'username' (a nil value) stack traceback: /usr/lib/prosody/core/rostermanager.lua:104: in function 'load_roster' /usr/lib/prosody/core/rostermanager.lua:305: in function 'set_contact_pending_out' mod_roster_command.lua:44: in function 'subscribe'

Introduction
============

mod\_net\_dovecotauth is a server implementation of the Dovecot
authentication protocol. It allows you to authenticate e.g. Postfix
against your Prosody installation.

Due to missing support for virtal hosts in this protocol, only one host
can be supported.

Configuration
=============

Install and add to modules\_enabled like any other module.

    dovecotauth_host = "example.com" -- Must be a defined VirtualHost

Compatibility
=============

Works with 0.9
