Please post the error message, which occurs within ISPConfig.
If you're using ISPConfig, you should be able to enable Maildir under Management > Server > Settings > Email.
But if it does not functioning and for the time being, you can also add the next line at the end of your /etc/postfix/main.cf file:
home_mailbox = Maildir/
Restart Postfix afterwards with: /etc/init.d/postfix restart
