| This is an external module.
Please note that it may or may not work with the current release (1.8.2).
This module is not included in the default ZNC installation, and you will need to manually compile it before you can load this module.
Contact the author if you have any questions, but feel free to ask on #znc (chat.freenode.net). Someone might be able to help you there.
Buffers are stored if all your clients are disconnected, or marked as away. This module allows you to send an /away to ZNC marking the client as away. While all your clients are away or disconnected, ZNC will store buffers. These buffers include any channel buffer with AutoClearChanBuffer and private message buffers.
This module has a secondary use, which is auto away. Auto away allows the module to forward your /away to the real server once all clients are away, or all clients are disconnected. If a single client doesn't have the away set, you are not away. Without auto away enabled, any /away sent to the ZNC server will not be forwarded to your IRC server.
This module can be used as a solution for FAQ#How_to_store_private_messages_even_when_user_is_attached.2C_so_other_clients_can_see_them.3F by setting the client as /away.
The source can be found at https://raw.github.com/kylef/znc-contrib/master/clientaway.cpp . Compatible with ZNC 1.0 and onwards.
