Hi friends,
I know many commercial web server control panels like Plesk. But what I am looking for is an open source solution in order to meet all of the requirements of a production web,mail and DB server,A solution that you have had positive experience with it.
Thank you

I haven't used it for much, but you could try webmin (google for it). RHEL ES comes with Red Hat Network.

Just some suggestions.

Dear friends,
By web hosting control panels I mean one kind of software that we can manage a web server,it differs from webmin in many terms.for instance you may define different quatas for customers and define different policies for resellers to sell our space.In addition most of these programs will help you to manage other services like mail servers.In this category you can define for exmaple maximum 30 mailbox for a customer owns mycust.com domain. I belive that if you check Plesk you will find out what I mean!
Notice : ISPConfig is also recommended.(Opensource).But I have not tried it yet.
Thank you,

And like I said, I have never tried either, they were the first things that came to mind. I'm doing better than the other, non-existant posters so far

Hope you find a working solution

Yes, you can done it by Webmin, but u need its extra modoule that called ViertualMin. Click here http://webmin.com/index8.html for more details. After setup Webmin you need to add new modoule Virtualmin also. Here Virtualmin user guide http://www.swelltech.com/support/vir...ers/index.html . Check it out and pls tel me know. I use that for Intranal network, and that works fine and I hope it works also for real life.

Dear friend ,
Thank you for your solution.I have installed related module in webmin but I got an error message regarding my postfix onfiguration.I will write the result here as soon as I gained a positive income.
