## 1. Introduction

VMailMgr (short for Virtual MAIL ManaGeR) is a package of programs designed to manage multiple domains of mail addresses and mailboxes on a single host. It co-operates with qmail for mail delivery and program control.

## 1.1 What is VMailMgr and why should I use it?

VMailMgr is:

A series of utilities for managing virtual domains which include a password checking interface for qmail which replaces the usual checkpassword, and an authentication module for Courier IMAP, that provide access to the virtual mailboxes by one of three methods:

- IP-based virtual server access (invisible to the POP3 user)
- username-based access (username-virtualuser)
- hostname-based access (virtualuser@virtual.host or virtualuser:virtual.host)

You should use it if:

You prefer to have each domain controlled by a seperate username, allowing the use of system quotas and better security
