DNS and Name Servers Setup Help:
"The next type of record you might want is called a REVERSE NAME MAPPING (ptr) record. This functions much like an A record, except that it maps an IP address to a name, instead of the other way around. This record is not required, but many administrators like to have it for completeness, and some mail servers won't deliver to other mail servers without a ptr address."
