如何阻止HELO是IP地址的SMTP连接请求?
例如:
Mon 2015-12-07 00:16:39: Session 1730; child 1; thread 652
Mon 2015-12-07 00:16:38: Accepting SMTP connection from [112.91.82.122 : 2343]
Mon 2015-12-07 00:16:38: --> 220 silverp.cn Mdaemon ESMTP MAIL ready
Mon 2015-12-07 00:16:38: <-- HELO 112.91.82.122
Mon 2015-12-07 00:16:38: --> 250 silverp.com.cn Hello 112.91.82.122, pleased to meet you
Mon 2015-12-07 00:16:38: <-- MAIL FROM:<>
Mon 2015-12-07 00:16:38: --> 250 <>, Sender ok |
