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.
Install and add to modules_enabled like any other module.
dovecotauth_host = "example.com" -- Must be a defined VirtualHost
Works with 0.9
With the plugin installer in Prosody 0.12 you can use:
sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_net_dovecotauth
For earlier versions see the documentation for installing 3rd party modules
