Vpopmail

vpopmail is a free GPL software package, to provide a way to manage virtual e-mail domains and non /etc/passwd e-mail accounts on qmail mail servers. Originally developed by Inter7

Features

• Support for 1 to 23 million virtual e-mail domains using a "grow as it goes" balanced directory tree.
• Support for 1 to 23 million e-mail users per domain using the same balanced tree structure.
• Automates all qmail configurations into scriptable command line programs and documented API library calls.
• Automates Unix user/group/other permissions of directories and files.
• Supports authenticated relay control of qmail smtp servers.
• Needs only one user in /etc/passwd for all email accounts.
