The match section performs AND operation on different matches: for example, if you have from and rcpt in the same rule,
then the rule matches only when from AND rcpt match. For similar matches, the OR rule applies: if you have multiple rcpt matches,
then any of these will trigger the rule. If a rule is triggered then no more rules are matched.
