oMail-admin is a PHP-based Web front-end to qmail and
vmailmgrd. It can be used by administrators easily administer their mailboxes.
Its features include mailbox/alias management, support for auto-responder,
changing passwords, and translation in various languages. In oMail Admin you can
also create, edit, and delete mailboxes and aliases. All this can be done
through a browser without going trough the complications of qmail command-line
It provides two kinds access, namely administrator with all
rights and single user who can only change his own account access. Omail Admin
also has session expiration after a specified number of minutes, thus, providing
some security to the users.
qmail is a secure, simple message-transfer agent. It is
designed for typical Internet-connected UNIX hosts. It provides support for
SMTP, POP3 service, and queue management. qmail is vastly smaller than any other
Internet MTA. Other MTAs have separate forwarding, aliasing and mailing-list
mechanisms while qmail has a simple forwarding mechanism that lets users handle
their mailing lists. For this article we are assuming that qmail is installed
and already running on your system with virtual
|oMail Admin is an easy way to configure mailboxes in qmail using a web-browser|
vmailmgrd is a daemon for VMailMgr It is the local server
that is used to handle managing virtual domains from a Web or remote
interface.VMailMgr (short for Virtual MAIL ManaGeR) is a package designed to
manage multiple domains of mail addresses and mailboxes on a single host. It
cooperates with qmail for mail delivery and program control. It provides a local
delivery agent (vdeliver) for delivering mail to virtual users, a checkpassword
replacement (checkvpw) for authentication, a courier-compatible auth module (authvmailmgr)
for authenticating with courier-imap, courier-pop3d, and a suite of tools for
VMailMgr provides administrators full control over their
own extension addresses and gives the users control over virtual domains.
Each virtual domain is assigned to a system user, and all
of the information about the domain is stored in that user’s home directory.
To install download latest tarball of VMailMgr from http://www.vmailmgr.org/,
unpack it and browse to the directory where you have unpacked VMailMgr and run
# make install
Before we start configuring VmailMgr, we need to configure
qmail to recognize the domain. To do this, you need to modify two of qmail’s
configuration files in `/var/ qmail/control’. These are: `rcpthosts’ and `virtualdomains’.
All you need to do is:
|In oMail Admin you can easily assign every user a particular quota, maximum message size etc|
To `rcpthosts’, add the line `mydomain.org’. To `virtualdomains’,
add the line `mydomain.org: myuser’. In the next step we have to configure qmail
to use VMailMgr’s checkvpw instead of qmail’s password checker.
Configure qmail-popup/qmail-pop3d to use `checkvpw` as the
password checker. This depends on how you have installed qmail.
Replace `checkpassword` in the command used to invoke qmail-
popup/qmail-pop3d in `/etc/inet.conf` or in a `tcpserver`command with `checkvpw`.
Now that you have your user added to the system, you’re
ready to set the user up to receive a virtual domain. For this, issue the
# su username
vsetup: created users directory.
vsetup: wrote ‘.qmail-default’ file.
vsetup: added alias ‘mailer-daemon’
vsetup: added alias ‘postmaster’
vsetup: added alias ‘root’
|You can also create a new user account by clicking on the New Mailbox Account Link|
The ‘vsetup’ command will set up the base VMailMgr
files. By default it will add users mailer-daemon, postmaster, root to the
domain. To add other users and aliases, type the following.
vadduser new user
vaddalias myself me
vaddalias somename me
Here vadduser adds a new user to the virtual domain where
as vaddalias adds an alias.
After you have completed all these steps, you will need to
kill and restart qmail-send to make it read the new `virtualdomains’ control
file. VMailMgr supports Courier-IMAP but Courier-IMAP does not
autodetect VMailMgr. To make it autodetect VmailMgr, you must copy `/usr/local/bin/authvmailmgr`
to `/usr/lib/ courier-imap/libexec/authlib/authvmailmgr`.
Then modify the `AUTHMODULES` statement in `/usr/lib/courier-imap/etc/imapd.config`
and add `authvmailmgr` as the first authentication module.
Configuring oMail Admin
After vmailmgrd is up and running, we will configure oMail Admin. Before you
start configuring oMail Admin make sure that PHP is installed on your system.
Now unpack all oMail Admin files in htdocs directory. Next
/etc/httpd/conf and open the
Now open PHP.ini file and set
If “index.php” is not defined as DirectoryIndex
in your Apache conf, replace the $script_url = “$SCRIPT_URL”; line in
config.php by $script_url = “$SCRIPT_URL/index.php”
Now, open your browser and then type the URL for oMail-
admin. Type your domain (yourserver.com) in ‘Email Address or Domain Name’
box and the domain password.
Then, click on Login and a new page with account management
should come up.
Once you are logged in, you will see the list of the qmail
users and their mailboxes. To edit settings of any user, click on Settings tab.
A new pop-up window will appear. Here you can customize the quota and other
settings of the users.
