Components of an Internet Mail System
IMail Server provides the following basic services required to implement an Internet-based mail system. (The illustration on the next page shows these components.)
- An SMTP server which lets IMail Server communicate with other mail servers on the Internet.
- A POP3 server which lets an email client retrieve mail from the mail server.
- An IMAP server which provides another method whereby an email client can access mail on the mail server.
This guide focuses on setting up the mail server; however, you also need the following software components to connect your mail system to the Internet and to provide mail capabilities for your users:
- A Domain Name System (DNS) server. The DNS server can be on your network or hosted by your Internet Service Provider.
- E-mail client software for each mail user, such as Microsoft Outlook Express®, Microsoft Outlook ®, or Qualcomm Eudora®.
Alternatively, mail users can use IMail Server Web Messaging to read and send mail through a web browser.
