iManager: Virtual Subhosts

bullet iManager for Virtual Subhosts
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.


bullet Configuration
iManager authenticates a user by looking in the ~/etc/passwd file. Hence, any user with a valid Virtual Private Servers 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 Servers hostname, 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 Servers 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 Servers 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:

http://imanager.SUBHOST-DOMAIN.NAME/   or

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

  1. Order a CNAME record in the zone file for the Virtual Subhost's domain name. There is a nominal fee fee for creating custom CNames. 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.
