Karmasphere supports three Query Protocols. They are: BQuery, DNS, and XML/RPC.
We provide Client Libraries so your software can speak those protocols.
We also provide Client Plugins for common MTAs, based on those libraries.
If your reputation data is in a supported format, upload it to Karmasphere using our web interface.
For Unix jockeys, the karma-publish also submits to the web interface, but runs on the command line. It groks a wider range of formats so if you have data in, say, rbldnsd format, you will want to use karma-publish to preprocess.
Karmasphere is a multi-tiered system designed to be integrated with other networks and data distribution systems. Contact us if you're interested in more information.
If you're using a client library or software plugin, join the Karmasphere Developers mailing list.
