Any INNd experts here who can answer this one? I've got everything working at the moment, INNd happily working with suck, storing articles from the german and cheesy servers, and sending any local posts back to the german server. Locally generated posts are identified by the INNd generated Message- IDs, suck greps these, strips them out and then posts them back to the german server. The problem I have is clients that create their own Message-IDs, as these can be anything, so they're not picked up by the suck script, and so not forwarded onto the outside world. I think I could do one of three things; 1 For any posts coming from clients in the local users auth in readers.conf, if a Message-ID exists, reject the post. 2 For any posts coming from clients in the local users auth in readers.conf, strip off the Message-ID. 3 Find some way of getting INN to write posts coming from a particular local users auth'd in readers.conf to a seperate file, then suck doesn't need to grep round to find the locally generated posts. I think 1 will be the easiest, but I can't figure out how to do any of the three ways?
