I have setup Kerio Mailserver and can email myself and send email to other domains and they receive it fine. I cannot receive email from external or other domains. What am I missing here? This is a new domain that is hosted but I don't want to push the pop3 mail to this server as I feel it would be better to receive the email directly is this correct? If so what have I not done correctly?

We have a static IP address lets say of and I am assuming this address needs to be set in dns somewhere but I don't know where. The company where the domain is hosted currently has a MX record and name servers and pointing to their servers. There is also a decicated ip address there as well. Lets say they are ip and names servers as ->

If anyone can point me in the right direction I would appreciate it. I never did find on the Kerio Mailserver anywhere to setup our own IP address. Thanks

For e-mail from outside your domain to be delivered to your Kerio server, you have to have an 'A' record that defines yur mail server's name, and an 'MX' record defined for your domain.

If your domain is '', and the IP address of your mail server is, you need:

*) an 'A' record that defines '' as

*) an 'MX' record that points incoming mail for '' to ''

The kerio server should be configured to use the host name used in the first bullet

If you have a firewall or router between your mail server and the internet (good practice!), you need to use the external IP address of the firewall, and you need to configure the firewall to allow incoming SMTP traffic.

Hope this helps

I setup the A record and MX to point to our domain and ip address. After 24 hours I am still not receiving external email. I know it takes 24-48 hours but when using an online test to check my mx records they are correct. Not sure what else I need to do.

Use the host (*nix, osx) command or nslookup (all) to query the DNS.

eg. host x.x.x.x (lookup x.x.x.x using the default DNS of the current system)
host x.x.x.x y.y.y.y (lookup x.x.x.x using the DNS at y.y.y.y)

If the DNS looks ok, you should be able to telnet to the smtp port on your server using the domain:

telnet 25

It wouldn't hurt to check if your server is receiving smtp at all:

telnet x.x.x.x 25

If that doesn't work, check your firewall to ensure it is allowing port 25 traffic. The Kerio server should also have the smtp service running and accessible for the correct port - see "services" in the admin console.

It's been several days since your question, so I'm guessing you've likely already figured most of this out.

Good luck,
