    Code:

    Firewall are set correct to allow port 25/110 inbound/outbound

    Anyone can point out the right direction to test or look for more details as I have no idea where to test if it work. When sending email from Corp email or Gmail I will not get a respond saying email is undeliverable or doesn't exist, general I presume it have dropped the email during the routing. I have also set correctly on my MX record and A record.

    I have a feeling that whether if this issue is related to my ISP static IP address routing with them.
    I have run mx lookup and PTR on mxtoolbox.com and result as below, thish IP address point to 60-242-90-39.static.tpgi.com.au, instead it should or not be "Stevengiang.org.au"? Please correct me.

    Code:

    Type 	IP Address 	Domain Name 	TTL
    PTR 	60.242.90.39 	60-242-90-39.static.tpgi.com.au 	48 hrs

    This subject has been covered many, many times in the forums, if you're behind a NAT router then you will need a Split DNS set-up - go to the wiki article and read what's need and how to configure and test it.

    You've also posted various dig commands with no output other than log file entries.

    I confused now and I would require to install bind9 again? since I follow LHammonds guide here My Notes for Installing Zimbra OSE on Ubuntu Server 10.04 LTS
    Which I thought I have already configure DNS resolution, I did follow to install dnsmasq but port 53 were being used by bind9 and couldn't start?

    Sorry, I did a copy & paste and the code was not the code, I run the command and result as below
