Lines: 17 Interpreting host!user@host2 as @host2:host!user or @host1.uucp:user@host2 is equally valid since there isn't a standard for mixed addressing. Sites that run an internet mailer give higher precedence to the "@" while UUCP only sites tend to give a nod to "!". Many sites also offer "%" as a low precedence version of "@". Nobody is offering parentheses "()" as grouping characters, unfortuately. rfc819 says that domains are interpreted right to left but doesn't recognize "!" as meaning anything. The moral is: when in doubt, use source routing. -- Internet: lee@rochester.arpa UUCP: {decvax, allegra, seismo}!rochester!lee Phone: [USA] (716) 275-7747, -5671 Physical: 43 01' 40'' N, 77 37' 49'' W
