How do you plan to set your MX record? Normally an MX record needs to resolve to an A record, which needs to resolve to a specific IP address.

Hi sgpeter

If you want to run a mail server, you need at least basic knowledge of DNS, SMTP and TCP/IP. Although KMS makes it very easy to setup a mail server, it is not enough to start setup.exe and run the wizard.

There are some external factors to sending and receiving mails. These are:

- Firewall / Routers (with NAT)
- Internet DNS
- Internet Domains

At minimum you need to indicate two DNS Servers for your domain and then you should enter an A record and an MX record into these servers. This is simpler for public static addresses but also possible for dynamic IPs.

If you don't know how to do that this is maybe the wrong forum. You should go to

http://www.nic.net.sg/sub_links/dns_basics.html

to learn the basics of DNS.

How do you get incoming mail? Don't you have outbound mail bounced because your IPs are in dynamic IP blocks?

Dear freakinvibe,

Really appreciated your kind explanation . after reading the KMS Administrator’s Guide , we have some idea of an A MX record , then I learn that free domain Tool only has a function of Switch you dynamic to specific IP address. But any Advance function you need to pay it .

Actually , we still have some confusion , but I would try to learnt more .

Thank you very much .
