    I'm curious if there is anything that I could learn how to configure my ispconfig with my account because I do not have static IP. Any help would be appreciated.

    I'm using dnsexit and zoneedit for my domain. works with ispconfig also.

    I never use before.

    All you need only some dynamic ip program update.
    set all of ISPconfig 's LAN IP only. You can't use dns manager as full feature.

    All I wanted for this to work are web, ftp and email.
    Web works fine..
    FTP works fine..
    Email doesn't work so I'm wondering since you said that I can't use DNS manager which I need to create MX for email? Should I use TZO's outbound mail relay for this?

    According to their site (solution for sendmail)) is to put this "define('SMART_HOST','') in but I'm using postfix. Where do I edit this?

    Thanks Till,

    I'm able to send out any emails now by using the relay host setup. My ISP blocks 25. Grr! I'll attempt to try if I can use other ports by modify the smtp settings.

    Now I have one more left to do which is how to make it work so that I can receive email on my server.

    I have created MX acct at for and still my server doesn't pick up any emails.

    Can ya help?
    Many Thanks.

    Maybe port 25 is also bloked for incoming emails. Please check that the MX record of your domain points to the external IP address of your router and that you forwarded port 25 from your router to your server.

    Port Test


    I checked and found a port tester that I could determine if any of ports are blocked or not.

    Using nmap -A -p 10-800
    and this is what I get:
    Starting Nmap 4.10 ( ) at 2007-06-25 11:33 EDT
    Interesting ports on d36-143-153.MY-ISP-SITE (XXX.MY.IP.XXX):

    It is bit weird that the ISP says that their port 25 is blocked and the nmap is showing it as open port.

    Is this useful information for myself to check the ports?

    Um, that won't work, your local to yourself, not going through the providers network...

    You need to do this remote from your server...
