php – 完整的邮件标题

我需要一组邮件头连接到PHP中的mail()函数.我发送带有HTML的电子邮件,有时像Yahoo Mail这样的服务阻止它们.因此,我需要确保我至少提供正确的标题.

我的代码：

// To send HTML mail, the 'Content-type' header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= 'From: MyCompany <[e-mail]>' . "\r\n";  

还有什么我应该补充的吗？

解决方法:

    $headers  = "From: testsite < [e-mail] >\n";
    $headers .= "Cc: testsite < [e-mail] >\n"; 
    $headers .= "X-Sender: testsite < [e-mail] >\n";
    $headers .= 'X-Mailer: PHP/' . PHPversion();
    $headers .= "X-Priority: 1\n"; // Urgent message!
    $headers .= "Return-Path: [e-mail]\n"; // Return path for errors
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=iso-8859-1\n";
