Your A record does not match that IPv4 addr: (mdh@kirin) [~/]# host 23.227.197.10 10.197.227.23.in-addr.arpa domain name pointer horsezipsworld.com. (mdh@kirin) [~/]# host horsezipsworld.com horsezipsworld.com has address 23.227.197.11 You may want to set something up like mail.<domain> which points to 23.227.197.10 and then set the PTR for 23.227.197.10 to mail.<domain> so that you have a matching set. PTR's that don't match are unreliable - I can set a PTR for my IP addresses to matt.google.com, but that doesn't mean I have any authority regarding google.com. Take care, Matt
