Example Three

In this scenario, a small company is * not * connected to the Internet but would like to setup local email service for it's employees. They have a network setup with a variety of Windows95/98/2000 systems. The computers use Internet protocol (TCP/IP) but do not have access to a name server (DNS). We'll use NETBIOS name resolution for this example. It's the basic method and automatic if nothing else is installed. If you want to use a private domain name in addition to the NETBIOS names, you will have to use a HOSTS files. See Trouble Shoot for more information on name resolution.

Each computer is uniquely identified by an IP address and a computer name. The mail server will be a Windows 2000 system called PostOffice. To send a message to Bob address it to bob@postoffice.

Install the SMTP Server

You can use the instructions shown on the Installation page to install the SMTP server.

Configure the SMTP Server

Email Server Name

We want the name of the email server to be PostOffice for this example, but you can name it anything you want. Right click on My Computer on the desktop. Select Properties from the menu and then select the Network Identification tab. Click the Properties button to change the computer name. You will have to reboot for the new name to take effect.

Domains

We won't use a domain name here. The email messages are just sent to the email server called PostOffice so we'll just use the computer name. To send a message to someone, address it as someone@postoffice.

To configure the SMTP server, go to the START button > Programs > Administrative Tools and select Internet Information Services. There should be a single computer listed and it if it was installed it should have a Default SMTP Virtual Server. If you expand the Default SMTP Virtual Server there are two items. Domains and Current Sessions. When you click on the Domain, the default local Fully Qualified Domain Name (FQDN) should be shown in the right pane. In this case it will be PostOffice.

That is it, unless you want to enable logging. Click on the General tab to set this.

Although we have a number of computers using this SMTP server, all the messages are destined for this computer so we don't have to set anything for relaying. This is the (start and) end of the message loop.

Install the POP3 Server

You can use the instructions shown on the Installation page to install the POP3 and POPAgent services.

Configure the POP3 Server

Open the EMWAC IMS applet from the Control Panel. On the first tab called Directories, use C:\Inetpub\mailroot\Users\%USERNAME% for the Mailbox Directory. Click the Automatically Create Mailbox option ON. For the Mail Spool Directory use C:\WIN2000\System32\LogFiles. For the Postmaster put in your logon username.

On the Misc tab, click the Copy local failure reports to postmaster ON. In the Accept Mail For: add the domains that are listed in the SMTP domains setup above. In this case, simply add PostOffice. Type it in the lower box and click the Add button.

On the Logging tab, click the POP3 Log Enabled. Then click the OK button to close the dialog box and apply the changes. You will be given a warning about stopping and starting and server before the changes will take affect. Do this. Go to the Control Panel > Administrative Tools and select the Services applet. Find the IMS POP3S Server, right click it and pick Restart from the menu. Do the same for the IMS POP Agent.

Create a IMSUsers Group

Any user that you want to be able to receive mail must have a valid account on this computer and belong to the IMSUsers group. In Windows 2000, use the Advanced tab of the Users and Passwords Control Panel applet to add a new group. In the left pane, right click Groups and select New Group from the menu. Type in IMSUsers and a description if you want: Email users for PostOffice or something like that will keep things documented. If you have existing users you can add them now with the Add button.

The group also must have the Logon as a batch job privilege. Use the Local Security Setting in the Administrative Tools of the Control Panel to add the IMSUsers group to this policy. Pick Local Policies > User Rights Assignment, then double click Logon as a batch job item. Click Add and add the IMSUsers group to the policy.

Create User Accounts

For all the users that want to use the email, you must create an account for them on this computer in addition to any accounts they have on other computers. You may or may not want to make the username and passwords the same as the accounts they have on the other computers but it might be a good idea to keep things simple. Simple works best.

In Windows 2000, use the Advanced button tab of the Users and Passwords Control Panel applet to add a new user. Once the new users are created, you can either right click on the user and use Properties from the popup menu to make them a member of the IMSUsers group or right click on the group and use the Properties item to add users to the group. Either way works.

Setting up an eMail Client Program

Because this is a Windows network, we'll use Outlook Express for the client program to send and receive email messages. However, because this is a standard email server setup, you can use any email client program, including Netscape Messenger or Eudora.

From one of the computers that you want to enable the email client, logon to an account on that computer. Open Outlook Express. The Internet Connection Wizard should automatically start. If not, pick the Tools menu, and select Accounts. Click the Add button and select Mail. In the Internet Connection Wizard, fill in the name you want to appear on the email messages and click Next. Select the I already have ... option and fill in the new email address. This would be username@postoffice where username is the logon name of the account on PostOffice. Click the Next button.

The email server names are both postoffice. The incoming mail server is a POP3 server. Click the Next button. The account name is the username you used above and the password is whatever you assigned. Click the Next button. and then the Finish button to finish up. You can repeat this for any other accounts that your are setting up.

That's it for this example. Click the Continue button to see some trouble shooting tips.
