Specifying the scope of the rules
NOTE: The email flow for rules is part of the configuration of rules. See Creating rules.
Direction Select for which sender and recipient the rule should apply.
Address pattern Restrict the rule to certain address patterns or user groups.
NOTE: Use the MAIL-FROM domain or parts of it.
NOTE: The maximum number of configurable address patterns is 256.
NOTE: To get groups from a user directory, you must configure an automatic user import of LDAP or Active Directory users. Groups are available after the first synchronization has been performed. See Automating the user import.
