Question

有没有办法设置PHP mail（）的优先级？我查看了在线手册，但我找不到任何参考。

优先级，我的意思是标题中的高，正常，低或1,2,3。所以收件人知道邮件的紧急程度。

谢谢！

Answer 1

通常通过在标题中设置以下字段来完成：

“X-Priority”（值：从最高[1]到最低[5]的1到5），
“X-MSMail-Priority”（值：高，正常或低），
“重要性”（值：高，正常或低）。

请参阅以下示例（摘自php的邮件功能文档）：

<?php
        $headers = "MIME-Version: 1.0\n" ;
        $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n";
        $headers .= "X-Priority: 1 (Highest)\n";
        $headers .= "X-MSMail-Priority: High\n";
        $headers .= "Importance: High\n";

 $status   = mail($to, $subject, $message,$headers);
?>

Answer 2

<?php 
        $headers = "MIME-Version: 1.0\n"; 
        $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n"; 
        $headers .= "X-Priority: 1 (Highest)\n"; 
        $headers .= "X-MSMail-Priority: High\n"; 
        $headers .= "Importance: High\n"; 

        $status = mail($to, $subject, $message, $headers); 
?>

Answer 3

使用第4个参数中的X-Priority标头调用它：

mail ( $to, $subject, $message , "X-Priority: 1")

Answer 4

A comment上的{p> PHP mail function documentation说：

<?php 
        $headers = "MIME-Version: 1.0\n" ; 
        $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n"; 
        $headers .= "X-Priority: 1 (Highest)\n"; 
        $headers .= "X-MSMail-Priority: High\n"; 
        $headers .= "Importance: High\n"; 

        $status   = mail($to, $subject, $message,$headers);

Answer 5

要定义邮件优先级，您必须将这些行放在标题中：

<?php 
        $headers = "MIME-Version: 1.0\n" ; 
        $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n"; 
        $headers .= "X-Priority: 1 (Highest)\n"; 
        $headers .= "X-MSMail-Priority: High\n"; 
        $headers .= "Importance: High\n"; 

 $status   = mail($to, $subject, $message,$headers); 
?>

除了我的问题之外，其他所有操作均不起作用

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= 'From: xyz@example.com' . "\r\n";
$headers .= 'Cc: Admin@example.com' . "\r\n";

PS：电子邮件正文必须在标题之前。
