This problem is probably due to the stupidity of the way some systems interface with the network (Peter, no need to protest, you know I'm stubborn about this). When I send a file to user XXX at the average MVS/WYLBUR node with TAG DEV PUN nodeid XXX, it does NOT get to XXX's reader. It will either end up printed on some line printer, discarded, placed on hold, etc. What you must do is TAG DEV PUN nodeid XXX W=XXX. This will tell TSO that the destination for the file is XXX. Yeah, I know, it seems obvious that XXX is the destination since you've put it in the TAG. But if you don't use W=XXX too, the guy just won't be able to access his file. I've fixed that in 1.5g and I'm nearly sure that the CDC problem comes from this missing W=. Could they try it out on my server and see if it works. You may have noticed a frenetic series of PUT PEERS NAMES commands on your server. They're due to the problems I encountered with the distribution of the command, due mainly to the fact that the CUNYVM entry contained incorrect information (incorrect version tags, hardware "3090-4" (the latter is not a problem but it confirms the fact that the entry was not ok)) which caused the BITNIC server not to forward the distribution to CUNYVM. It thought that CUNYVM was a release 1.5 (base 1.5) server and wanted to protect it from a security hole that affected these servers, so it discarded the distribution. Sorry for all that overhead.
