PTR Record - How to set?

[gbradley]

Hello,

I am a newb to the server area. I am having problems with oubound SMTP and I think I need to set the PTR Record. What is it? and how do I set it?

I think it is ...

blueboy.mydomain.com

The host name is "blueboy", right?

The domain is "mydomain.com", right?

So how do I setup a PTR? and a reverse DNS lookup?

Am I on the right track?

bradley...

you are correct. that is your host and that is your domain.

a ptr record is a reverse pointer to your domain name. normal for dns (aka name server) is a reference from name to ip, such as when you type www.serverbeach.com it goes through dns to find out the IP address is 66.139.72.12, then your system connects using that IP address.

a ptr record is so that a system who has an IP address can find your name... so if you have a ptr record for smtp.mydomain.com it would be an entry in dns like... 12.72.139.66-in.addr.arpa to www.serverbeach.com. it's the opposite of a regular dns lookup.

if you tell us your domain name, we can look up your domain info and check and see if it's ok. otherwise.. try going to http://www.dnsreport.com

they have a mail check as well.
