horsezipsworld.com has address 23.227.197.11
horsezipsworld.com mail is handled by 10 mail.horsezipsworld.com.

>host mail.horsezipsworld.com
mail.horsezipsworld.com has address 23.227.197.11

>host 23.227.197.11
11.197.227.23.in-addr.arpa domain name pointer horsezipsworld.com.


The above are inconsistent.  IPAddress -> Name =/= the found name -> IPAddress


>host 209.86.93.228
228.93.86.209.in-addr.arpa domain name pointer mx3.earthlink.net.

>host mx3.earthlink.net
mx3.earthlink.net has address 209.86.93.228

Thee appear to be consistent ...

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. which points to
23.227.197.10
and then set the PTR for  23.227.197.10 to mail. 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
