My exchange 2000 server was an open relay on ordb.org and has since been resolved. However we can't seem to get of the blacklist from dsbl.org. When I try to remove from their black list I get the following:
"Your server seems to believe it needs to relay for local addresses. This does NOT mean that it is closed to relaying, just that it is broken and does not accept and deliver local mail, albeit with a confusing error message. "
