php – 如何正确添加List-Unsubscribe标头？

You’re subscribed to this mailing list. Unsubscribe

检查我的Facebook邮件时我注意到了这一点.所以当我检查Facebook标题时,我注意到了这一行

List-Unsubscribe: <mailto:unsub+engage_digest_email@unsubscribe.facebook.com>
X-Priority: 3
X-Mailer: ZuckMail [version 1.00]
X-Facebook-Camp: engage_digest_email
X-Facebook-Notify: engage_digest_email; mailid=523199eG1fe9e7abG0Gd4
List-Unsubscribe: <mailto:unsub+engage_digest_email@unsubscribe.facebook.com>
Errors-To: update+pmhd_um@facebookmail.com
X-FACEBOOK-PRIORITY: 1

因此,通过我的phpmailer设置,我添加了addCustomHeader()函数.

$x = new PHPMailer();
$x->From = "support@veepiz.com";
$x->FromName = "Veepiz Support";
$x->AddAddress($o->emailaddress,$o->toname);
$x->AddReplyTo("support@veepiz.com","Veepiz Support");
$x->WordWrap = 80;                                 // set word wrap to 50 characters
$x->IsHTML(true);                                  // set email format to HTML
$x->IsSMTP();
$x->Host = "veepiz.com";
$x->Username = 'support@veepiz.com';
$x->Password = 'xxxxxxxx';                
$x->Subject = $o->subject;
$x->Body    = $o->content."nn<span style='color:white'>Forgotten your password? go to <a href='http://www.veepiz.com/forgot.php'>http://www.veepiz.com/forgot.php</a></span>";
$x->Body    = str_replace("r","n",wordwrap($x->Body,80));
$x->AltBody = $o->plain_text;
$x->AltBody = str_replace("r",wordwrap($x->AltBody,80));
$x->AddCustomHeader("List-Unsubscribe: <mailto:unsubscribe@veepiz.com?subject=Unsubscribe>,<http://www.veepiz.com/unsubscribe.php?unsubscribeid=$ox->id>");

现在,当我发送邮件时,我在邮件标题中得到了这个…

List-Unsubscribe: <mailto:unsubscribe@veepiz.com?subject=Unsubscribe>,<http://www.veepiz.com/unsubscribe.php?unsubscribeid=1>

似乎phpmailer正在添加此标头,它符合rfc http://www.list-unsubscribe.com/

但是在Hotmail中我没有得到组件显示我已经订阅了blah blah邮件列表取消订阅
