Most public Internet service providers employ these protocols, but some corporate intranets do not. Many companies are switching to Netscape Mail Server for their intranets because it offers both superior mail features and standard access to the Internet. Getting your message out can be as easy as using a list server to broadcast a mail message to all your subscribers. Messages are sent to the list server. The list server parses the mail list.
Mail travels over the Internet.
The client's mail server collects the messages. Netscape client software automatically recognizes and displays HTML-formatted material. To take full advantage of HTML mail you need a method for tailoring each mail message to its recipient's interests and demographics. For that you'll want a profiling system like Netscape Publishing System . Subscribers register their preferences with Netscape Publishing System using predefined HTML forms.
