I just noticed I haven't been receiving QWK mail since Aug 10th, and traced it back to the fact that I used to run with 10 nodes, but on Aug 10th I reduced that to 4 nodes.The problem was that I stupidly set my QWK call out node to 10, so after reducing the node count to 4 the call out node was invalid. As far as I can tell there were no errors or warnings displayed anywhere, so it took awhile until I finally noticed the call out node value and fixed it.Assuming it's not already logged somewhere and I just missed it, could an error be logged when an invalid call out node is detected?
