Is Direct Admin the one?

[inx]

I run a ISP in South Africa, we have our own control panel that we wrote in ruby on rails, our company is called ISP in a BOX. We have resellers selling all our ISP products under their own names, our system run the same way as DA or Cpanel, just home made, using postifix, power dns, apache etc. We are now looking at a more stable system that we can interface from our ISP in a BOX program (using API's).

What i'm asking is DA big enough to handle 40 000 mail boxes? not on one server but split over 4 servers.

I have googled Cpanel v/s DA v/s Plesk and read the a lot of users and admins say use Cpanel if you are a hosting company, but I we have installed Cpanel VPS and must say looking at DA demo Cpanel is very confusing.

Does DA have API's for me to interface with from my own program?

Will DA be able to handle a lot of traffic and users? Is DA the correct program for an ISP?

How does DA DNS servers work?

Only you can decide if DirectAdmin will work for you. It will certainly handle large numbers as long as you know how to configure your services to work in a high-volume environment. DirectAdmin itself is written in C++, and is quite independent of versions of software it uses.

DirectAdmin has an API that allows you to do just about everything you can do from the control panel itself.

The one thing DirectAdmin doesn't do is work transparently over multiple servers. I presume that what you want to do is have 40,000 mailboxes one one server for your ISP customers, not for your hosting customers.

You could do that in DirectAdmin by setting up a domain for each of your resellers. In this case the email login will be the entire email address.

Feel free to ask specific questions.
