    I think I am finally almost at the finish line of setting things up. :D

    Just one problem left I cant send any mails out.
    I am not on a isp who blocks port 25. The server is in a data center I red in a topic that i must forward port 478.

    I checked the firewall in ispc3 but there aren't any entry's do I have to make some?

    In the same topic its say to use the netstap -tap command so I did but to me its ??

    server1:~# netstat -tap

    Are the last causing the problem?

    I can sent email If I use the smtp server from my own isp in outlook, I hope that it's a small thing this time.

    Your server is in a DC, but is the clients PC who is trying to send email's maybe on a network that is blocking port 25?

    Of course I was thinking the wrong way.

    But My port isn't blocked (xs4all) I had my server first here at home and that worked fine.

    I found a solution but NOT the problem. If I use instead of all is working fine. Did I do something wrong with the cname records?

    Did you create an MX record for your domain? Please note that you must use an A record for an MX record; CNAME records are not allowed.

    And sad but true this is not my last problem, again my site is down?? and my mail server is working more not that it is working, boyh pop3 and smtp.
