Internet Protocols

The Internet is a collection of networks and gateways that use Transport Control Protocol/Internet Protocol (TCP/IP) to handle data transfer and message conversion from the sending network to the receiving network. An Internet protocol is a set of standards designed to enable different types of computers to communicate with one another and to exchange information through the Internet.

In addition to providing Simple Mail Transfer Protocol (SMTP) support, Microsoft Exchange Server supports the following:

• Internet News Service/Network News Transfer Protocol (NNTP)
• Post Office Protocol version 3 (POP3)
• Internet Message Access Protocol Version 4 rev1 (IMAP4rev1)
• Lightweight Directory Access Protocol (LDAP)
• Hypertext Transfer Protocol (HTTP) and Microsoft Outlook Web Access

You can set properties for Internet protocols at either the site or server level using the Microsoft Exchange Server Administrator program. You can also set properties on specific Internet protocols. For more information on configuring each protocol, see the appropriate chapter in Microsoft Exchange Server Operations.
