# The MxLookup method is deprecated:

# ------------------------------------------------------------------------
# Do the equivalent using the Chilkat DNS class

# This gets all MX domains for an email address.  (Typically one domain.)
# The preferred domain will be at index 0 (see below).

    json.I = i
    domain = json.StringOf("answer.mx[i].domain")

    i = i + 1
