Various versions of uucp have different rules for name truncation. Some use 7 chars (the majority) some use 6 (some System V uucp's--this was apparently an error that crept into a major distribution) and some don't truncate at all since they use separate directories for every site. These variations cause substantial compatibility confusion in some situations, but they can usually be worked out. For the purposes of sitename registration, the UUCP Project considers that sitenames must be unique in the first 6 characters (to deal with those "broken" System V uucp's) in order to be registered. However, sitenames may be LONGER than 6 chars (or even 7 chars) so long as they remain UNIQUE in the first 6. So, for example, "microsoft" is OK, even though it is 9 characters long--some software simply truncates the name. Eventually, under a domain-based system, many of the name uniqueness restrictions (for the domain-based addresses) will probably be lifted, though the underlying site transport name will still need to meet uniqueness restrictions to allow full intersite compatibility. --Lauren--
