这是我的代码：
$to = 'to@mail.com'; $subject = 'test'; $body = 'test'; $header = 'MIME-Version: 1.0' . "\r\n"; $header .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; $header .= "To: <$to>" . "\r\n"; $header .= 'From: from@mail.com \r\n'; mail($to,$subject,$body,$header);
代码有效,它会发送电子邮件.
但发件人不是我定义的那个.
发件人似乎是网络邮件主机.
我究竟做错了什么？
尝试设置信封发件人,并在邮件标题中设置发件人,如下所示：
$to = "to@to.com"; $from = "from@from.com"; $subject = "subject"; $message = "this is the message body"; $headers = "From: $from"; $ok = @mail($to,$message,$headers,"-f " . $from);
