If the server isn't set up to relay to a hub machine or forward via mailertable, then it should automatically reject any address that is not a local account. Maybe you have PostmasterCopy enabled. Look in sendmail.cf to be sure that #O PostmasterCopy=Postmaster has the leading # to comment it out. I've forgotten the sendmail.mc invocation that would enable it but these days you probably don't want it on. Virtusers is mostly useful if you forward or accept for more than one domain or wish to appear to. -- Les Mikesell lesmikesell@xxxxxxxxx
