iManager empowers your Virtual Subhost customers to manage their own accounts using the comfortable, easy-to-use iManager environment. Available features include:

  • Changing their password and viewing their quota and usage
  • Uploading and editing files to their home directory
  • Sending and receiving e-mail through the web-based Mail Manager

Additionally, iManager will help you successfully manage the configuration of Virtual Subhost e-mail accounts.


iManager authenticates a user by looking in the ~/etc/passwd file. Hence, any user with a valid Virtual Private Server User Account can access iManager with their login and password. Access will be granted only to the user's home directory. If you have configured a user account for your Virtual Subhost customers, then they can access iManager using the Virtual Private Server IP address, like this:


The users would simply use their user account login and password in order to authenticate. It is also possible to configure your Virtual Private Server so that a user can also access iManager using their own domain name, like this:


or something more generic like mail instead of imanager, for example:


To use either one of the above urls, you would add one of the following Alias directives to your web server configuration file (~/www/conf/httpd.conf).

Alias /imanager/ /usr/local/etc/httpd/htdocs/imanager/
Alias /mail/ /usr/local/etc/httpd/htdocs/imanager/

Of course, you can choose any alias name that strikes your fancy. You would simply need to replace /imanager/ or /mail/ in one of the previous Alias directives to be whatever you wish.

An alternative way to configure your Virtual Private Server so that a subhosted domain name can access iManager is to use a canonical domain name such as imanager or mail. Consider the following examples:


To enable access to iManager in this way, complete the following steps.

  1. Add a CNAME record in the zone file for the Virtual Subhost's domain name (contact ITS Technical Support to do this). We suggest using imanager or mail for the CNAME record (for example, imanager.SUBHOST-DOMAIN.NAME or mail.SUBHOST-DOMAIN.NAME), but you can specify any name you want.

  2. Add the following <VirtualHost...> directive to your web server configuration file (~/www/conf/httpd.conf).

    <VirtualHost imanager.SUBHOST-DOMAIN.NAME>
    ServerName imanager.SUBHOST-DOMAIN.NAME
    ServerAdmin webmaster@SUBHOST-DOMAIN.NAME
    DocumentRoot /usr/local/etc/httpd/htdocs/imanager
    TransferLog /dev/null

    or alternatively:

    <VirtualHost mail.SUBHOST-DOMAIN.NAME>
    ServerName mail.SUBHOST-DOMAIN.NAME
    ServerAdmin webmaster@SUBHOST-DOMAIN.NAME
    DocumentRoot /usr/local/etc/httpd/htdocs/imanager
    TransferLog /dev/null

    NOTE: If you would like to use a different canonical name, then substitute the CNAME record you created for imanager or mail above in the VirtualHost and ServerName directives. Do not change the DocumentRoot directive.
