    How can it be backscatter when it is from a local domain within the local server. Without seeing the headers from a email it is almost impossible to say; though I reckon the headers will show DNS_FROM_OPENWHOIS and FH_DATE_PAST_20XX are hitting. Therefore the OP should read the following threads :
