Additionally, you may want to set these variables:

• postfix_smtpd_milter : list of milters, either socket prefixed with unix: or IP address prefixed with tcp:, see here for more info
• postfix_non_smtpd_milter: list of milters for messages that, either socket prefixed with unix: or IP address prefixed with tcp:, see here for more info
