postfix收不到邮件。 Helo 命令未经授权
Postfix not receiving mail. Helo command Unauthorized
OS: Ubuntu 12.04
邮件版本：Postfix 2.9.6
发件人能够收到我们的邮件，但是邮件没有出现在我们的邮箱中，我不明白为什么。

我特别不明白 Helo command Unauthorized-2015-240 部分。

我什至不知道从哪里开始。
我找到了！在 /etc/postfix/helo_access.pcre 中，有这个正则表达式模式：
/.*\.co$/ DISCARD Unauthorized-2015-240
与日志中的消息匹配：
Helo command Unauthorized-2015-240
所以我添加了正则表达式以允许该特定域：
/.*o1.ptr3680.wellable.co$/ OK
然后重新加载 Postfix，再次尝试时收到了电子邮件。
