无法理解为什么我得到这个错误 – 无论是从邮件地址是有效的（我每天都在使用它们），所以无法弄清楚这是怎么发生的 – 任何帮助，将不胜感激。
注：这是在生产中工作，但是在dev中抛出错误。 我有更严格的configuration在开发。 注意：我正在使用smtp4dev在PC上进行本地testing
$to = 'recipient <[email protected]>'; $cc = 'copy <[email protected]>'; $from = 'sender <[email protected]>'; $filename = 'Invoice#'.$order_id.'.pdf'; $message = file_get_contents(ROOT_DIR.'admin/include/email-body.html'); $content = chunk_split(base64_encode($pdf_file)); $uid = md5(uniqid(time())); $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'To: '. $to . "\r\n"; $headers .= 'Cc: '. $cc . "\r\n"; $headers .= 'From: '. $from . "\r\n"; $headers .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n"; $headers .= "This is a multi-part message in MIME format.\r\n"; $headers .= "--".$uid."\r\n"; $headers .= "Content-type:text/html; charset=iso-8859-1\r\n"; $headers .= "Content-Transfer-Encoding: 7bit\r\n\r\n"; $headers .= $message."\r\n\r\n"; $headers .= "--".$uid."\r\n"; $headers .= "Content-Type: application/pdf; name=\"".$filename."\"\r\n"; $headers .= "Content-Transfer-Encoding: base64\r\n"; $headers .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n"; $headers .= $content."\r\n\r\n"; $headers .= "--".$uid."--"; if (mail($to, $subject, $message, $headers)) { print "SUCCESS"; } else { print "FALIED"; } 如果我在mail（）行打印variables，结果如下：

你的$必须只是邮件地址。 SMTP对话框需要使用尖括号中的邮件地址，并将To：标题的内容提供给它。 $也是一样的。
