I have been googling around a bit, but wanted to ask in a forum to see what people's experiences are. Has anyone tried to host their own pyzor or razor2 server to coincide with a spamassassin server? It seems to be possible with pyzor, but I am not sure about razor2. According to what I think I am seeing in the pyzor mailing lists, one can setup a server, but there is no way to sync it with a "main server" or collaborative network. It sounds like if you do install a pyzor server, you are a lone server with no link to other servers for syncing datasets.
From what I read with razor2, I am uncertain of being able to mirror anything or setting up your own server.
states that the servers connect to Cloudmark. so I am uncertain on this one. I couldn't find much so far. (but still looking into it)
Any pointers in the right direction or help in understanding would be great.
