my has problems sending mail to earthlink.net the sever has a ptr abd
reverse dns set but i get this To: jimmy@horsezipsworld.com
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
host 23.227.197.10
10.197.227.23.in-addr.arpa domain name pointer horsezipsworld.com.
host horsezipsworld.com
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 ...
