The Fuzzy Zone setting instructs SBBSecho to ignore the zone information in the netmail message header. If the netmail itself had an INTL kludge, it would use the zone information from that, but makenl isn't adding it. So, with Fuzzy Zone behavior, SBBSecho will "guess" the zone information based on the destination net/node/point. It's an arcane feature for old pre-historic "stored messages" and probably should just be removed.
