PHP邮件功能不会向同一域上的有效帐户发送电子邮件

Question

我正在使用邮件功能如下:

mail($emailto, $subject, $body, $headers);
mail('askme@mysite.com', $subject.' / '.$emailto, $body, $headers);

第一个是针对最终用户的.第二份副本是我保存记录的.

Soometimes最终用户指定他们的电子邮件地址,其他时候是空白.

1. 指定电子邮件地址后,最终用户实际收到电子邮件时没有任何问题
2. 但是,在EITHER情况下,没有电子邮件发送到askme@example.com - 我也检查了垃圾邮件文件夹.

在我的/ mail/new文件夹中,我看到许多FILES创建类似于下面的内容.错误是错误的,因为askme@mysite.com是一个有效的电子邮件地址(使用谷歌设置域名).

  Return-path: <>

Answer 1

两件事情:

1. $emailto在实际调用mail函数之前,您应该检查是否为空.您不希望PHP尝试将邮件发送到空白地址.

2. 您askme@mysite.com未交付的问题可能是由于您的本地网站托管(mysite.com)尝试将邮件发送到其认为的"本地"地址 - 因为它位于同一个域中,而实际上该电子邮件存在于Google Apps中.您的邮件服务器(如postfix或sendmail)应该有一个设置来禁用此"快捷方式".
