Multi-valued Form

Multiple SIEVE scripts per user can be stored in LDAP. To enable the user interface to handle several smaller rules scripts, rather than one script containing all the domain’s rules, this attribute takes multiple values (that is, multiple rules). The server looks at every rule in mailSieveRuleSource.

To provide ordering and possible user interface editing information, there is an optional SIEVE comment line in each rule. This line has the following format:

# $Rule Info: Order=(1-infinity, or 0 for disabled)

All rules that have a Rule Info line will be processed first by the Messaging Server. If Order=0, then this rule is not used in the SIEVE evaluation. Otherwise, the rules are processed in the order provided (1 having highest priority). To accommodate SIEVE rules that might not have been entered using the Rule Info extension, any other rules found are run by the server, in order received from LDAP after all rules with corresponding order values have been processed.
