我已经测试以下代码几个小时了。电子邮件将发送到通过添加的地址，$mail->AddAddress()并且在收到的电子邮件中注明抄送，但抄送人没有收到电子邮件。我到处寻找，找不到解决办法来解决为什么会发生这种情况。我已经运行了测试，并且所有变量都正确地提交给了这个代码。
我的服务器正在运行 Linux Red Hat
我的代码：
require_once('../smtp/class.phpmailer.php');
//include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded
$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
$mail->IsSMTP(); // telling the class to use SMTP
try {
$mail->SMTPDebug = 0; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "tls"; // sets the prefix to the server
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = $port; // set the SMTP port for the GMAIL server 465 or 587
$mail->Username = $username; // GMAIL username
$mail->Password = $password; // GMAIL password
// Add each email address
foreach($emailTo as $email){ $mail->AddAddress(trim($email)); }
if($cc!=''){ foreach($cc as $email){ $mail->AddCC(trim($email)); } }
if($bcc!=''){ foreach($bcc as $email){ $mail->AddBCC(trim($email)); } }
$mail->SetFrom($emailFrom, $emailName);
$mail->AddReplyTo($emailFrom, $emailName);
$mail->Subject = $subject;
$mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
$mail->MsgHTML($content);
// $mail->AddAttachment('images/phpmailer.gif'); // attachment
// $mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
$mail->Send();
echo'1';exit();
} catch (phpmailerException $e) {
echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
echo $e->getMessage(); //Boring error messages from anything else!
}
