Please note: This page is incomplete and refers to some third party module. OpenSimulator developers are not responsible for third party code (or indeed for OpenSimulator code itself, but that's a different point).
Offline messaging makes it possible to send IM's to people that are not online and saves the messages directly to a database.
Through PHP module
In the latest version offline module is already ready to be used
- Install the Offline_IM.sql file on your database (xampp http://www.apachefriends.org)
- Enable the Offline Messaging Module in your Opensim.ini file.
- Uploadt the offline.php to your web server(xampp http://www.apachefriends.org).
Changes in the OpenSim.ini file
[Messaging] ; Control which region module is used for instant messaging. ; Default is InstantMessageModule (this is the name of the core IM module as well as the setting) InstantMessageModule = InstantMessageModule ; MessageTransferModule = MessageTransferModule OfflineMessageModule = OfflineMessageModule OfflineMessageURL = http://yourserver/offline.php MuteListModule = MuteListModule MuteListURL = http://yourserver/mute.php ForwardOfflineGroupMessages = true
When you did it right, reboot your region and try to send a message to an offline person. Check the database to see that it has written a record.
Next time that person logs in, he will get the message and the database will be updated
P.D: The MuteListModule and URL must be uncommented in order for the offline module to work, even if there is no mute.php file in the web folder.
