我被告知在 stackoverflow 中重新发布此内容,因为它实际上可能不是后缀问题。但是,我对 php postfix 交互性知之甚少,所以如果脚本部分有问题并且有人可以看到它,请告诉我。我不确定是否有一种特殊的方法可以让邮件正常传递(输入或输出),一旦它通过脚本,如果这甚至是问题。谢谢!

--

当我工作的时候,我做了一个我在做什么的指南,以备将来使用。我一直试图让它工作一段时间,并且我已经让电子邮件通过脚本。问题是所有收到的邮件,被退回或以其他方式,在收到邮件并且脚本完成运行后没有被放入邮箱。我可以补充一下,该脚本确实运行并在内部执行了所有操作,并且没有错误地退出。

  1. 添加目录:$sudo mkdir /usr/local/bouncehandler

  2. 将脚本文件添加到 /usr/local/bouncehandler:mybh.php

  3. 允许执行脚本:chmod a+x mybh.php

  4. 添加用户:$sudo useradd 弹跳

  5. (创建 /etc/postfix/virtual_aliases 以添加一个包罗万象的别名——localuser 需要是现有的本地用户:bounces@bounces.mydomain.com root:)这整个步骤已被删除

  6. 创建 /etc/postfix/transport 以添加传输映射。“mytransportname”可以是任何你想要的;它在下面的 master.cf 中使用:mydomain.com mybh:

  7. 接下来,transport 和 virtual_aliases 都需要编译成 db 文件: ($sudo postmap /etc/postfix/virtual_aliases) REMOVED $sudo postmap /etc/postfix/transport

  8. /etc/postfix/master.cf 中的更改:smtp inet n - - - - smtpd (-o content_filter=mybh:dummy) 已移除

  9. 将传输添加到 /etc/postfix/master.cf: mybh unix - nn - 10 pipe flags=q user=bounce argv=/usr/local/bouncehandler/mybh.php ${sender} ${recipient}

  10. /etc/postfix/master.cf 中的更改:

    拾取 fifo n - - 60 1 个拾取 (-o content_filter=mybh:dummy) 已移除

  11. 在 /etc/postfix/main.cf 中:

transport_maps = hash:/etc/postfix/transport (virtual_alias_maps = hash:/etc/postfix/virtual_aliases))已移除

  1. 连接数据库并创建表bounce_list:

    如果不存在则创建表bounce_list(电子邮件VARCHAR(255)NOT NULL PRIMARY KEY,bounce_count INT(4)NOT NULL)ENGINE = InnoDB;

  2. 重启后缀:

$sudo 后缀重新加载

我通过它的脚本检查收件人是否是我的域,我相信这表明它是发送给我的。如果是,我检查它最初是否发送给其他人,如果是,我检查用户并将电子邮件视为已退回。我没有在脚本中做任何其他事情,所以我不确定在那之后我是否应该调用原始邮件脚本(如果有的话)。

我已经包含了所有我认为可能有用的信息,这些信息来自我在阅读许多指南和许多其他帖子时看到的必要信息,并试图自己弄清楚这一点。

如果一双新鲜的眼睛可以帮助我,我将不胜感激。

  • 我还想知道,如果有人知道如何执行此操作,请将原始目标电子邮件附加到退回的电子邮件中。

谢谢

因此,当您添加过滤器时,您基本上是在说我会从这里处理事情,所以为了仍然接收退回邮件,您需要将邮件发送给原始收件人。

// original bounce handling code

// Now resend the bounced message
// get message from stdin
$fp = fopen("php://stdin", "r");

$message= '';
while (! feof($fp)) {
    $message.= fgets($fp);
}

// send to original recipient, lazy but easiest just to pipe the message in to sendmail
shell_exec('echo ' . escapeshellarg($message) . ' | /usr/sbin/sendmail -G -i ' . $recipient);
