postconf -e smtpd_recipient_restrictions="permit_mynetworks,reject_unauth_destination,reject_unknown_recipient_domain"
测试发现上现这个写法并没有起到我想要的作用,可能是规则应用逻辑上不是我理解的那样会把所有的规则检测一次,而是在某个规则适合了就终止检测了.所以需要写成下面的写法,因为它符合了permit_mynetworks?所以就不检测后面的条件了.
postconf -e smtpd_recipient_restrictions="reject_unknown_recipient_domain,permit_mynetworks,reject_unauth_destination"
执行上面那句更改配置的命令即可
像这些规则类,在顺序上需要注意,如果顺序恰当,就会提高效率,因为前面的规则已经过滤掉大部分不合法的请求.
Specify a list of restrictions, separated by commas and/or whitespace.Continue long lines by starting the next line with whitespace.Restrictions are applied in the order as specified; the firstrestriction that matches wins.
看它的说明应该是只要..的关系,即跟||一样的判断逻辑
reject_unverified_recipient
表示直接在smtp交互时把已知不可达的,会被弹回的,域名不存在的拒绝,但是这个如果验证没配好话.就会出现smtp连接上了,但是交互命令发送过去后没有反应的问题.直到超时连接自动退出的情况.还有就是这将会占用系统很多资源
reject_unknown_recipient_domain:拒绝收件人域名不存在的请求;如果没有设置这个,postfix会先收信再检测发信.
