In the proposal RFC 1033(?) underscore was mention. But this RFC never got offical. Read RFC 1035, 1123(?) and 1912. Esp. in 1912 it tells you common errors of DNS config errors. And especial the underscore and / are mentioned. Regards, Ulf. At 08:28 AM 1/16/97 -0500, Stephen F. Combs wrote: >Jaye, > Underscores are NOT LEGAL in domain/host names.
