User Accounts
Only authorized users of the server can access some facilities offered by "Rainmail Server". These include the "File Server" , "Email Server", "Fax Server", "VPN Server", "VoIP Server" and the "Chat Server". When you want to provide such facilities to a user, an account corresponding to the user must be created. A user account not only makes sure that the user gets access to the facilities, but also makes sure that unauthorized users are not allowed to access these facilities.
Each user account in the computer must have a unique name. A password is associated with every user account. Authorized users need to enter both their account names and passwords to get access to facilities. In the following sections, we will look at how to create and manage user accounts.
To add a user account, you must have the following information ready:
- User ID: This can be derived from the user's real name, but should be limited to eight characters.
- User Password: This is the password with which valid users can access their account. It is best to avoid common names and easily guessed words as passwords. As a policy, we require that passwords be at least six (6) characters long and recommend that they contain at least one special character (like %, $, &, etc.).
- User's actual Name: Usually account names are cryptic, as they are limited to eight (8) characters. Therefore, the system also required you to add their real name in a separate field. This helps in maintenance of the system.
- Once you have this information ready, start up the "Rainmail Server" configuration program. Click on "Add User Account" in the left-hand side. That will bring up the following screen:
3.2.1 Adding User Accounts - RIS Standard
Adding an user account helps you share the resources of your system with your employee/client/staff. To create the account, decide on the username you are going to assign to the user. The username is at most 8 characters long, and wherever possible you should choose their first name, or first name and first initial if a user account already exists.
In the above screen, enter all the required information. The password that is entered is not displayed on the screen and therefore, we require you to enter it twice. If your configuration consists of an email domain, then the name of account will be the prefix you entered in "User ID" field followed by the name of your email domain. In the above case, the full account name will be "user.icsoft", where icsoft is the email domain name. If you do not have an email domain, then the account name will be just the value that you have entered in the "User ID" field.
- Emailid: This will be a word with no spaces or special characters. Valid account names can only include alphabetical characters. Examples of valid account names include "basha", "moorthy" and "priya". There are no limits on the number of characters an account name can have, but we do recommend that it is no more than eight (8). Examples of names that are not valid account names include "9isnotvalid" (because it contains a number), "sita.gita" (because it contains ".", a special character) and "douhavea$" (because it contains "$", a special character).
- User ID: If you do not have multiple domain, then the login name will be just the name that you have entered in the "User ID" field. Otherwise, this field gets emailid name as the userid, which appears automatically as the "Email Id" is typed. In case of multiple domain, the login name of the user account will be composed of 5 character domain prefix followed by the "Email ID". So if the domain prefix is "cariz" and the Email ID entered is "priya" then the User ID will be "carizpriya".
- Password: This is the password with which the user can access the resources on the system (be it mail or files). It needs to be at least six (6) characters long. When you type this in, the letters will not be reflected on the screen for security reasons. Therefore, we need you to type this in twice (Once in the "User Password" and once in the "Confirm Password" field).

Adding an user account helps you share the resources of your system with your employee/client/staff. To create the account, decide on the username you are going to assign to the user. The username is at most 8 characters long, and wherever possible you should choose their first name, or first name and first initial if a user account already exists.

Once you enter these values, click on "Add" button and the specified user will be added to the system. A message box will be displayed on the successful completion of the process.
User accounts can be deleted, thus permanently denying the user access to facilities offered by "Rainmail Server". All of user's data in the system are deleted when an account is deleted. Please make sure that user's data is not required before deleting the user from the system. To delete a user's account, open up the configuration program and select "Delete User Account" from the left-hand side. That will bring up the following screen:
WARNING!!!! This will delete all data currently present in user's home directory. Please make sure that the data is not required before completing this operation.
In the above screen, select the account to be deleted from the "User ID" field, and press "Delete". In this case, Do you want to delete temp@carizen.com? yes/no dialog appears. Click yes to delete it permanently.
3.4 Disabling / Enabling User Accounts
Do not remove an account right away, but first simply disable it, especially if you are working with a corporate server with lots of users. After all, the former user may one day require the use of his or her account again, or may request a file or two which was stored in their home directory. Or perhaps a new user (such as an employee replacement) may require access to the former user's files. In any event, make sure you have backups of the former user's home directory, &ldquojust-in-case&rdquo.
User accounts can be temporarily enabled/disabled. This feature is useful to temporarily allow/deny access to users to the facilities offered by "Rainmail Server". When an account is disabled, user cannot log in to access email or see files on the server system. To enable/disable user account, bring up the configuration program and select "Disable/Enable Account" from the left-hand side. That will bring up the following screen.
In the above screen, select the name of the account you want to dis(en)able. The current status of the account will be displayed. Press on the "Disable" or "Enable" button to make the necessary change. When you enable an account, "Rainmail Server" resets the account password to blank. Therefore, we require that you immediately provide a new password to the enabled account.
It is good policy to keep changing the user passwords frequently. That will keep the system secure. To change a user's password, bring up the "Rainmail Server" configuration program, and click on "Change User Password" in the left-hand side. That will bring up the following screen:
In the above screen, select the name of the user whose password is to be changed from the "User ID" combo box. Enter the user's current password in the "Present Password" field (leave blank if there is no password). Enter the new password twice (once in "New Password" and another time in "Confirm Password" field). Press "Change". For security reasons we require the password to be at least six (6) characters long and we recommend that it have at least one special character.
"Rainmail Server" gives minimal permissions to internal users by default. For example, any new user created does not have the following access:
- FTP Access : FTP stands for File Transfer Protocol. An FTP access allows transfer of files to and from the server.
- Shell Access : Telnet is a program that allows a person to run arbitrary commands by logging in to the server.
- External Access: Encrypted remote shell sessions are available through SSH to access the server through internet.
These permissions are useful for remote access and execution of applications. Only the "Mail Administrator" user is given all these permissions. This section allows you to change the settings for individual users. For example, if an user wants to access her mails from the outside, you have to give the user "External Access".
To change the permissions for an user, select user's account name from "User ID" combo box. Then, check the permissions you want to give the user using the respective check boxes. Pressing the "Set" button gives the set permissions to the user. Successful completion of this operation is indicated by a dialog.
3.7 Set maximum users - RIS Standard
The Rainmail Server is licensed based on the number of user license purchased. This information is validated at the time of installing the software. However, after installation if you have purchased additional <n>user license, (n= 25 or 50 or 75 or 100), you have to increase the number of users, inorder to create additional users. To set the user license, bring up the "Rainmails configuration program" and select "Set Maximum Users" in the left-hand side panel. This will bring the following screen:
To increase the number of licensed users, enter the maximum number of users, your license allows you to create using the "Number of Users" field. Enter your license password in the "License Key" field. Please take care to enter the license key as given in your letter. License Key is case sensitive and are exactly thirty two (32) characters long. Press "Set". If the password entered is valid, the system will validate your license and will issue a success message.
