我有一个通过Php mail()函数发送电子邮件到gmail的问题。我用我的雅虎邮件测试了这个脚本，没有问题(电子邮件正文没有附件)。下面是我的代码:
$mailto = "info@email.com";
$charset = "utf-8";
$subject = "subject text";
$content = "text/html";
$headers = "MIME-Version: 1.0'n";
$headers .= "Content-Type: $content charset=$charset'n";
$headers .= "Date: ".date("Y-m-d (H:i:s)",time())."'n";
$headers .= "From: '"".$mailto."'" <".$mailto.">'n";
$headers .= "X-Mailer: My Send E-mail'n";
$message = "message text";
mail($_POST['posEmail'],$subject,$message,$headers);
使用phpmailer类，它更安全，更容易使用。它支持附件和类似的
$headers .= "Content-Type: $content; charset=$charset'n";
内容和字符集之间的分号?
并尝试以'r'n结束，而不是'n。
$headers = 'To: ' . $epost . "'r'n";
$headers .= 'From: ' . $mailto . "'r'n";
$headers .= 'Message-ID: <' . $ordernummer . ">'r'n";
$headers .= 'MIME-Version: 1.0' . "'r'n";
$headers .= 'Content-Type: text/plain; charset=UTF-8' . "'r'n";
$headers .= 'Content-Transfer-Encoding: quoted-printable';
这些头文件有效。我还收到了名为noname.txt的附件邮件。
我添加了Message-ID, Content-Transfer-Encoding，从To和From中去掉了实名，跳过了电子邮件周围的<>，去掉了text/plain和UTF-8周围的引号，我大写了
你只需要编辑你的php.ini然后把这个
SMTP = smtp.gmail.com
smtp_port = 25
sendmail_from = youremailid@gmail.com从PHP页面使用GMail SMTP服务器发送电子邮件
