Configuring NNTP Posting Limits and Moderation Settings
Topic Last Modified: 2005-05-18
Exchange Server 2003 uses NNTP to enable users to participate in newsgroup discussions. Exchange also enables users who are running client applications that support NNTP to access newsgroup public folders on computers that are running Exchange. Users can read and post items, such as messages and documents, to NNTP newsgroups that are represented in Exchange as public folders. For example, users can share information by posting messages to a newsgroup public folder in their area of interest. Other users can read and respond to items in the newsgroup. Items in newsgroups can be replicated to USENET host computers through newsfeeds.
A newsfeed is the flow of items from one USENET site to another. Newsfeeds enable users of different news sites to read and post articles to newsgroups as though they are using one news site. A news site is a collection of related newsgroups. An article posted to one news site is sent to other news sites where it can be read. You need to create a newsfeed to each remote server to which you want to distribute news articles.
Because the reason for using newsgroups is to post and share information, you will likely need to manage the size of these postings in relation to the resources available on the NNTP virtual server. Accepting articles that are too large or accepting too much data during one connection can cause increased traffic, overload your network, and quickly fill your hard disk. Be sure to set a size limit that matches your server's capabilities.
