您好，我开发了一个时事通讯脚本来发送 HTML 电子邮件。
一切都很好地接收到桌面电子邮件客户端，但我注意到当我发送到 gmail 帐户时，html 链接不起作用，而嵌入的图像、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>
我发现了一些主题，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) { //一般标头 $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);
}
