My suspicion is that the person's who cannot receive the messages are over their disk quota. It is possible to have over quota conditions without getting a specific over quota bounce message. I have seen several of these lately. They can check their MSU AFS quota with an 'fs listquota' command or call the help desk for help with quotas. Of course, some other problem might be happening. But, as I say, I have see several of these over quota situations lately. If they are over quota, they may have to contact the help desk to get enough files removed so they can actually get on to clean up their files (messages/folders, etc). ////jerry > > -- > Oscar Castaņeda > Remote Sensing & GIS > Michigan State University
