VPopMail Virtualized Email

Handling virtual domains is a common issue posed by new users in the qmail and postfix communities. Inter7 has developed vpopmail (vchkpw – buipopmeil), a free GPL software package, to provide an easy way to manage virtual email domains and non /etc/passwd email accounts on your qmail or Postfix mail servers.

Features include

• Support for 1 to 23 million virtual email domains using a “grow as it goes” balenced directory tree.
• Support for 1 to 23 million email users per domain using the same balenced tree structure.
• Automates all qmail configurations into handy and scriptable command line programs and documented API library calls.
• Automates Unix user/group/other permissioning of directories and files.
• Supports authenticated relay control of your qmail smtp server.
• Virtual email file/directories can be assigned to any user/group or do the default vpopmail/vchkpw 89/89.
• Does not require email user accounts in /etc/passwd
• Supports name or IP based virtual domains
• Optionally automates support for:
  • Storing clear text passwords to help tech support workers
  • Record last authentication and automates deletion of stale accounts.
  • Storing alias/forwards in mysql or oracle
• Configurable logging based on real world admin’s comments and requirements.
• Support for Mysql, Oracle, PostgreSQL, /etc/passwd, /etc/shadow LDAP, Sybase, and default cdb authentication storage.
• Delivers directly to Maildir for use with qmail-pop3d, .qmail files or any other Maildir program.
• No need to have hundreds of .qmail files for virtual domains. Each domain gets it’s own directory under vpopmail user with a separate password file for each domain.
• Documented command line programs that can be used in scripts or for remote admin.
• Documented C library for all vpopmail features and transactions.
