HTML链接向Gmail发送电子邮件时出错

您好我已经开发了一个通讯脚本来发送HTML电子邮件 .

一切都很好接收到桌面电子邮件客户端，但我注意到当我发送到一个Gmail帐户时，html链接不起作用，而嵌入式图像，CSS，表格布局工作得很好 . Gmail更改

<a href="myurl" title="My url">link</a>

至

<a title="My url">link</a>

我找到了一些主题，没有解决方案 .

这就是我构建电子邮件的方式，在$ body var中是标准的html链接：

function send_mail（$ from，$ to，$ subject，$ body，$ site_skin，$ site_name，$ site_url）{// general header $ header =“From：$ site_name \ n”; $ header . =“BCC：$ to \ n”; $ header . =“X-Mailer：PHP5.3 \ n”;

//separator string
$boundary = "==String_Boundary_x" .md5(time()). "x";

// specific message header
$header .= "MIME-Version: 1.0\n";
$header .= "Content-Type: multipart/related;\n";
$header .= " boundary=\"$boundary\";\n\n";

//this part is viewed only if the program cannot manage the MIME
$message = "your software dosen't support MIME\n\n";
$message .= "--$boundary\n";
$message .= "Content-Type: text/html; charset=\"utf-8\"\n";
$message .= "Content-Transfer-Encoding: 7bit\n\n";

$title_newsletter ="$subject";
$mail_body = $body; 
$subject = "$titoloNSL";
$mail_site_url="$site_url";

include ("../../../../themes/skins/$site_skin/email/email.php");
$message .= "$htmlBody";

$message .= "--$boundary\n";
$message .= "Content-ID: <header>\n";
$message .= "Content-Type: image/jpeg\n";
$message .= "Content-Transfer-Encoding: base64\n\n";

$embedded_file = "../../../../themes/skins/$site_skin/images/mail_header.jpg";
$file = fopen($embedded_file,'rb');
$data = fread($file,filesize($embedded_file));
fclose($file);

$data = chunk_split(base64_encode($data));
$message .= "$data\n\n";

$message .= "--$boundary\n";
$message .= "Content-ID: <go>\n";
$message .= "Content-Type: image/gif\n";
$message .= "Content-Transfer-Encoding: base64\n\n";

$embedded_file = "../../../../themes/skins/$site_skin/images/go.gif";
$file = fopen($embedded_file,'rb');
$data = fread($file,filesize($embedded_file));
fclose($file);

$data = chunk_split(base64_encode($data));
$message .= "$data\n\n";

$message .= "--$boundary--\n";

@mail($to, $subject, $message, $header);

}
