PHP mail() - 如何设置优先级？

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

这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); 
?>
