We will use Outlook Express as email client.
A wizard starts. Use the following table to complete the wizard:
| Display name | Bob |
| E-mail address | bob@<your domain> (bob@ilopia.com) |
| Incoming mail server is a | POP3 |
| Incoming mail server | <your domain> (ilopia.com) |
| Outgoing mail server | <your domain> (ilopia.com) |
| Account name | bob@<your domain> (bob@ilopia.com) |
| Password | bob |
| Remember Password | Checked |
| SPA | Unchecked |
Are we finished now? Well, let us try to send an email. Didn’t work, did it? I’m sure you got an error message similar to this one:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'webmaster@ilopia.com'. Subject 'Test', Account: 'ilopia.com', Server: 'ilopia.com', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for webmaster@ilopia.com', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
The reason why we got this is written in the error message. “Unable to relay for <email address>”. This means that we didn’t get authenticated to the SMTP server. So, let us take a look at the email client’s settings again.
This will bring up this window:
And hopefully you will receive an email within some minutes (if you sent it to your own email account).
Of course we want our network as secure as possible, so we prefer to use SPA (Secure Password Authentication). This will, as stated before, send the user name and password from the client encrypted, instead of clear text.
We must also change some settings for the email clients.
If you need more help, or are curious about things, take a look at the help files in Windows Server 2003. They are excellent and you will find out that there are more features that I have not talked about.

Q. I have configured the email server and I can send emails without problems. But all emails the server receives ends up in the Drop folder and are not moved to the proper mailbox. What is wrong?
This can happen if you have moved the mail root recently and forgot to cycle the server. To cycle it, open the Services snap-in and find Simple Mail Transfer Protocol (SMTP) in the list. This problem can also occur if you created the SMTP account manually through the IIS snap in. What you have to do in this case is to delete the domain from SMTP and then re-add it using the POP3 tools.
Q. Does the built-in email server support Internet Access Message Protocol (IMAP)?
No, the built-in email server does not support IMAP. If you want or need IMAP support you'll have to look at Exchange 2003, Exchange 2000 running on a Windows 2000 Server machine in a Windows Server 2003 domain, or use a third party email server.
Q. I want the users to be able to read and write email from Internet. Does the built-in email server offer a web interface?
No, the built-in email server is very limited and is only a basic email server. So this feature is not included in it.
Q. I cannot find the SMTP Snap-In in IIS Manager. How do I get it back?
This is a known issue, and should be fixed in Service Pack 1 for Windows Server 2003. To fix it, follow these steps:
Uninstall and re-install the SMTP Service will not fix this.
Q. Where are the POP3 logfiles?
The POP3 Service logs to the Event Logs, which can be viewed by using Event Viewer.
