    I want to use ISPConfig just a mail server for some sites.

    For example has the web and mail server in Server1, has the web server in Server2 and the mailserver in Server1, I have another machine working as DNS, but I see that ISPConfig has its own DNS.

    How should I configure ISPConfig to act as mailserver for some sites and as web/mail server for others? Should I configure both DNS?

    You don't need to use the DNS Manager if youalready have DNS servers. It's just an option.
    Now create your web sites both on the web server and on the mail server. In the web server ISPConfig you select "External Mailserver" under Options and Co-Domains for all the domains of that web site. That's it. :)

    It seems to work, partially. Let me explain.

    * We have three boxes: One Windows 2003 Server hosting most of web servers using ASP, another Win2003S hosting the DNS and now one box with ISPConfig which is going to be the mailserver for the domains in the other boxes. The name of the Linux box with ISPConfig is

    * First case: We wanted to host (web and mail in the Linux box where ISPConfig is installed) and redirect web trafic from this domain to, it suceeded. I just created a site with, and added a directive "Redirect /". Then I created a mail account [email protected]. I can check the account from Thunderbird and web with no problems and the web only redirects.

    * We wanted to add, this time web in the Win2003S and mail in the Linux machine with ISPConfig. This didn't work. I added a site and created a sample account [email protected], I have no access to the DNS directly but the webadmin told me that configured web to the ip of the Win2003S and mail exchanger to my Linux box with ISPConfig. Unfortunately when I send a mail to [email protected] it is bounced back, and says that the account does not exist.

    Any suggestion? I haven't set up a mail server before and everything went almost smoothly (thanks by the way) until now, but I think that I have achieved most of the task :D, I just need to finish it.

    Have you checked the logs on the linux server, that the mail is really bounced by this server?

    Have you set in the site settings on the tab options and for the co-domains to local mailserver?

    Is in /etc/postfix/local-host-names?

    Is the email address listed in the postfix virtusertable?

    After checking the logs it seems that I'm not getting the mails after all, the DNS simply points to another machine (the one with IIS).

    In fact I tried to verify the records externally (using and there are no MX records for my, I'm going to try to solve it in the Windows 2003 Server DNS.
