Hi,
It is only applicable to the domains that are not known, ie no DNS Resolution. So based on your request, it could accept all the domain that have a DNS, even if they dont have an MX record.

Does it mean that only domains with both A and MX record will be accepted? Or, it means any domains with only A record,domains with only MX record or with both will be accepted. Can anyone clarify it? Thanks! I just want to block the senders whose domain without MX record, even if it has an A record. Thanks! Daniel Zhou
