We are planing for mail hosting, we are going to host multiple customer mail domain on single public IP. Now how i am going to set PTR record per customer? because i have single IP and it has to be single PTR enty.. If my customer running Mail Test tool online then he is getting error Reverse DNS does not match SMTP Banner

Any suggestion?

The forward and reverse DNS need to match. The name itself does not matter.

For example in my domain (ziobro.info) I have a record: rack2 IN A 162.219.7.27

My provider has a record: 27 PTR rack2.ziobro.info. in their corresponding in-addr.arp file.

One of my mail domains (ziobro.rochester.ny.us) has the appropriate MX recod:

ziobro.rochester.ny.us. MX      42 rack.ziobro.info.

Just repeat the MX record for each mail domain you host.
