Adding an Article Expiration Definition

To add a new article expiration definition, follow these steps:

1.From the Administration utility Main menu, choose Manage Components.

2.On the Manage Components menu, choose InterNetNews.

3.From the InterNetNews Administration menu, choose Modify Article Expiration Definitions.

4.From the Modify Article Expiration Definitions menu, choose Modify Article Expiration Definitions.

5.On the Modify Article Expiration Definition form, specify the following:

•Choose All, Moderated, or Unmoderated from the New Article Expiration Definition list box to apply the new article expiration definition to moderated newsgroups only, to unmoderated newsgroups only, or to all newsgroups (the default).

•Newsgroup Pattern—Specifies the newsgroup, or newsgroups, to which the article expiration definition applies. The newsgroup pattern can be one of the following:

◦A specific newsgroup (for example, rec.photo).

◦A list of newsgroups, separated by commas. For example, misc.*,alt.*,comp.*. Use the asterisk (*) to indicate all newsgroups within a particular category.

◦A newsgroup category or subcategory preceded by an exclamation point (!) indicates that the access privilege is not applied to that newsgroup category or subcategory. For example, the string misc.*,comp.*,!rec.photo* applies the access privilege to the misc.* and comp.* categories, but does not apply the privilege to the newsgroup rec.photo and all its subcategories.

Because the entries in a list of newsgroup patterns are interpreted in order, specify patterns from most general to most specific.

•Click on Add. The Add Article Expiration Definition form is displayed.

•Specify the following:

a.Keep Articles Without Expiration Headers—If an article in a newsgroup matching the newsgroup pattern does not have an expiration header, the value in this field specifies the expiration limit (the default is two days). If you specify to keep articles indefinitely, articles without expiration dates never expire.

b.Keep Articles With Expiration Headers—Articles with expiration headers specify a minimum and maximum number of days to keep expired articles. Use the radio
