Reverse DNS Plesk
Hi,
I have a website running on my dedicated server for a client and their mail is hosted on another server in house (in their office).
I have the domain set up in Plesk 11 and the DNS records look like the below example.
206.225.92.236 / 24 PTR domain.com.au.
ftp.domain.com.au. CNAME domain.com.au.
domain.com.au. NS ns1.dedicatedserver.net.au
domain.com.au. NS ns2.dedicatedserver.net.au
domain.com.au. A 206.225.92.236
domain.com.au. MX (10) remote.server.com.au.
remote.server.com.au. A 120.151.251.171
www.domain.com.au. CNAME domain.com.au.
Now...because i have the MX records pointing to the external mail server (remote.server.com.au - 120.151.251.171) do i need to make a PTR record for it?
Do i need to remove the PTR record that was made default with the domain?
Also i was wondering what the subnet would be? I see Plesk asks for that too when creating a PTR record...I'm still pretty new to DNS setups.
When i test SMTP through MX Toolbox i get the following warning: SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner
Can someone please help :) Thanks.

Thanks for the answers so far. So i don't need to set any PTR records in plesk for any domains, its all handled through the server provider? My DNS template in plesk has a PTR record set for new domains, can i delete this?

OR:
In the interim, you can configure exchange to identify itself as whatever the existing rDNS resolves to. Usually something like 120.151.251.171.Their.ISP.
