Hi Zopers, i have a general problem. May someone can help me. the users of my site should be able to lay down their content on the site (creating their own websites / like tripod) and they should have the possibility to get an email acount. user@myserver.com Every user should have the possibility to use pop3 to get his mail from the server. At the moment I am using Zope (with Medusa) and Apache. I want to use Zope but i dont know if there is a limit of users on the site (performance). I think 5 000 users are to many??????? I thought about using mySQL to handel the useracounts (I think there is already aproduct for this), but whats about the content of the users. Should the content be stored into the zope database or can I store the content at the linux filesystem? I thought about saving the data under /home/siteuser//content for example (by using a python funktion???) but then I have to use the useradd linux command and I am not quit sure if this work. Security? Is there a way to add user in linux? I think that can be a solution for the pop3 email problem. I hope I was able to explain my problem. I do not know much about Linux and Python but I have to find a solution. Any suggestions about this? Thank you for your help Jens
