Hello!


I am currently running Kerio Mail Server 6.7.0 7660 on Debian 5.0.3. The problem is that i can not receive mail FROM ANY SERVER from the outside world. I have added the domain right. I am absolutely 100% sure that my MX record is okay, because before kerio i used qmail and everything was fine.

It's behind a router, but every single port from the server is being forwarded and it's accessible from the outside world.

I can send emails.

The error logs isnt showing that there is any messages coming to the server.

If anyone have suggestions will be happy to read it.

As described in the error message, the problem is in your internet connection. It is blocking incoming connections on port 25 (SMTP):

the smtp is on port 26. But why the server is searching for mail.registrirai.me, my mx recod is for registrirai.me not for mail.registrirai.me?

1. SMTP *MUST* listen on port 25 if you want to receive emails from other servers. No exceptions.
2. Your MX record points to mail.registrirai.me as showed in nslookup output.

Read http://manuals.kerio.com/kmsag/en/sect-delivery.html and get some knowledge about email delivery in the Internet.

Hi Nikola,
I'm happy to help the customers with licensed software. Unfortunately, this does not seem to be such case. Our records show the opposite. So, all relevant informations have been logged for further investigation.
