Reverse DNS (PTR Record) for 2 servers on 1 IP

[abrodski]

Hello!

I just want to double check something...
I have 2 servers (HTTP and SMTP) sitting on 1 external IP (they share it) and they also share the same PC...
Both hosts have A Records...pointing to the same IP,obviously.
My mail server's host name is mail.domainname.com
Now...I'm asking my ISP to change a generic name that shows when someone does reverse DNS lookup of mail.mydomainname.com to mail.mydomainname.com
So my question is...if I'm doing is the right way,considering that I have 2 servers on the same IP?

Welcome to WebmasterWorld abrodski.

You lost me here.
You're trying to change an MX record, or a sub-domain?

Everything is fine.My ISP created PTR Records for reverse DNS check.So I think they whitelisted me...Not sure yet...sent them an e-mail...maybe you can tell me.
When I go to dnswl.org
I input my IP or mail server's host name and get this kind of message:

IP address 80.***.**.180 is listed at [dns service].org with the following details:
Domain: mail.example.com; Category: Retail/Wholesale/Service (127.0.**.x); Country: IL
Suggest change for this DNSWL entry.
DNSWL Id16983 - mail.example.com
IP range 80.***.**.180/32
Domain/Hostnamemail.refugee-forum.com
Scorelow

So...I'm whitelisted,right?
And what "score-low" means?
