To clarify, this is what we use on relay servers that do not have any 
local processes besides Postfix that need access. On servers where this 
is needed, such as for the use of 'sendmail', the '/etc/postfix' 
directory is kept world readable, as are the .cf files.

Everything that isn't part of the default config, such as map files, is 
kept inside a subdirectory inside '/etc/postfix', which has the limited 
permissions. That way the permissions on the files themselves are not 
as critical.
