I'm a little confused about the setup of a PTR record for reverse dns lookup.
We are hosted at Rackspace and we have a front end webserver and behind that an appserver. Users don't access the Appserver directly, they go through the webserver.
Webserver: www.domain.com 126.96.36.199 Appserver: app.domain.com 188.8.131.52
The appserver sends out all the email with from address suck as firstname.lastname@example.org
So, how do I set up the PTR / reverse dns configuration? I was thinking that it should be as follows:
Reverse dns record on Appserver:
184.108.40.206 = app.domain.com
A *.domain.com 220.127.116.11 A app.domain.com 18.104.22.168 TXT app.domain.com "v=spf1 ip4:22.214.171.124 ~all" TXT domain.com "v=spf1 ip4:126.96.36.199 ~all"
Would this be the correct way to set that up?
