PureMessage Sieve Extensions
policy.siv script uses extensions to the Sieve language to filter mail. Each
PureMessage specific extension is prefixed with
pmx_ to identify the action, test, or command as unique to the program. To
use these extensions include the command "
" at the beginning of the policy script. PureMessage
also provides the standard extensions
specified in RFC 3028. Note that both
included implicitly with
require "PureMessage";. See the pmx-policy manpage for more on specific PureMessage Sieve extensions.
Lastly, PureMessage has an extension for using regular expressions in match-type tests. See Regular Expressions.
