Hello,

I don't know I was clearly enough in the title, the problem is that one of my clients has his own mailserver, I host only his website, and he uses a local server for emails.

For the rest of websites which are hosted on this server, everything is ok, intodns.com reports this message :

You have reverse (PTR) records for all your IPs, that is a good thing.

But for the website which has the mailserver on another server it fails the PTR test on intodns.com

ERROR: No reverse DNS (PTR) entries. The problem MX records are:
2.218.77.82.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips


I have checked Tailor Made Servers control panel, and I have the option to set Reverse DNS for every IP alocated on my server, and for now all the websites (30) shares the same IP ..

Any advices ? 10x
