The Policy Repository stores Sieve rules that can be added to the PureMessage policy script. By default, the repository contains a number of general-purpose snipppets that can be copied and pasted to the PureMessage policy. Conversely, snippets can be added to the Policy Repository by copying and pasting rules from the PureMessage policy to the Clipboard or by adding Sieve files from the command line. The Policy Repository can be used to store complete Sieve scripts as well as snippets. For more about working with snippets, see "Managing the Repository" in the Manager Reference.
