Question

我有一个运行PHP和Exim4的Debian服务器（当然还有其他东西）。 PHP应用程序每天发送1000封电子邮件，所有这些都可以正常工作，但我现在有了一个新客户，我的PHP / Exim4无法发送到此帐户。

PS我添加了--at--来阻止抓取工具找到地址。

我检查了exim4日志，发现了这个：

2014-04-02 08:48:10 1WV7TW-0001Em-Od <= support --at-- sobs.com.au H=localhost [127.0.0.1] P=esmtp S=1215 
2014-04-02 08:48:11 1WV7TW-0001Em-Od ** az --at-- mentonegrammmar: Unrouteable address 
2014-04-02 08:48:11 1WV7TW-0001Em-Od Completed

然后我使用以下方法检查了exim4中的路由：

exim -d -f support --at-- sobs.com.au -bt az --at-- mentonegrammar

这看起来好像路由工作完美。我再次尝试了应用程序电子邮件，但仍然收到了Unrouteable地址错误。

然后我尝试了来自同一台服务器的命令行电子邮件。

echo“测试消息”| mail -s“测试消息”az --at-- mentonegrammar

此电子邮件已根据需要运行并已到达，但我的PHP应用程序中的电子邮件仍然失败。

我检查了申请表：

$mime = new Mail_mime();
$formattedHeaders = $mime->headers($headers);
$mime->setHTMLBody($body);
$content = $mime->get(array('html_charset' => 'utf-8'));
$smtp = Mail::factory("smtp", array());
$result = $smtp->send($headers["To"], $formattedHeaders, $content);

如上所述，此服务器和应用程序已成功发送了1000封电子邮件。
Mentone Grammar的IT部门未收到任何其他电子邮件的任何问题。

总之，我一直回到exim4日志中的'Norouteableaddress'错误，并且调试输出指示地址是可路由的。我不禁想到Exim4配置存在一些问题 - 但我只是不知道。

有人能指出我正确的方向吗？

Answer 1

解决方案就是在这个问题上。该应用程序的原始条目具有＃mentiegrammmar＆＃39;我后来的测试在哪里有＃ment; mentonegrammar＆＃39;。我的浏览器记住了应用程序的错误输入并自动填写表单，我没有注意到。

感谢krisFR在ServerFault中的答案。
