I checked with iptools:


65.98.62.138 is server5.kubeit.net.

Your server's reported hostname should match your rDNS record. According to the mail logs provided, your server is reporting its hostname as "server5.hostserver.net" which does not match the rDNS entry.

What do you suggest?

[garrettp]

Change the rDNS entry to match the server's hostname, or vice-versa.

I added a ptr record in dns zone but not work:

138.62.98.65.in-addr.arpa 14400 IN PTR server5.kubeit.net.

In my /etc/mailips I have this:

*: 65.98.62.139

I read this how to: Configuring Reverse DNS in WHM

You can only setup a PTR record if you control the IP zone file due to the IP provider delegating that IP control to you. Most ISPs and hosting providers do not provide IP zone control to their customers. If you do not control the actual IP zone, which is not the same as the DNS zone control, then the IP provider (whoever delegated the IP to you) will have to setup the PTR record.
