Domain Technologie Control (DTC) is a Web-based control panel for hosting that can delegate the task of creating subdomains, email, and FTP accounts to users for the domain names they own. It has support for many programs, including bind 8 and 9, MySQL, Apache, PHP 4, qmail, Postfix, Courier, Dovecot, ProFTPD, Webalizer, and mod-log-sql. It can also generate backup scripts, calculation scripts, and config files using a single system UID/GID, and monitor all traffic accounting per user and per service. It is fully skinnable and translated into several languages.
Virtual Exim is a PHP-enabled Web interface for managing multiple virtual mail domains with Exim and MySQL/PostgreSQL. POP/IMAP accounts, aliases, forwards, and permanent fail accounts can all be created and managed easily without the need for corresponding shell accounts. Virtual Exim also allows the server administrator to designate a SiteAdmin who can create and delete domains on the fly through the interface, so no editing of the Exim configuration file is required. Individual users can also log in to change their "Real Name", passwords, and mail filtering options with ease.
