php mail script not working using phpMailer - php

Question

I am using phpMailer to send emails using PHP.
The mail is being sent but it is not received in inbox/spam or anything.
It is surprising that it was working until few days ago.
I have tested it and almost 500-600 emails were sent and received.
But suddenly it stopped "working".
Here's my Php script:
public static function mailTo($recipients)
{
$f3 = \Base::instance();
$edit = $f3->get('editTrue');
$user = AclHelper::getCurrentUser();
$template= new \Template;
if(isset($edit))
{
$mailBody = $template->render('leave/requestEdit.html');
}
else
{
$mailBody= $template->render('leave/emailTemp.html');
}
// When true, PHPMailer returns exceptions
$mail = new PHPMailer(true);
try {
$mail->isSMTP(); // Set mailer to use SMTP
$mail->isHTML(true);
$mail->addAddress($user['email']);
$mail->addAddress("malakar.rakesh1993#gmail.com");
// foreach($recipients as $recipient){
// $mail->addCC($recipient);
// }
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587
$mail->Username = "malakar.rakesh1993#gmail.com";
$mail->Password = "abcd";
// $mail->Host = $f3->get('GBD.smtp.host'); // Specify main and backup SMTP servers
$mail->setFrom($user['email']);
$userFullName = trim(ucfirst($user['firstname'])) . " " . trim(ucfirst($user['lastname']));
$mail->FromName = $userFullName;
$mail->Body = $f3->get('message');
$mail->Body .="<br>". $mailBody;
if(isset($edit))
{
$mail->AltBody = '';
}
else
{
$mail->AltBody = 'Hello Team,<br>I would like to request leave for the leave dates specified as follows.
Application Date:' . $f3->get('issuedDate') . '<br>Leave requested from:' . $f3->get('leaveFrom') . '<br>Leave requested to:' . $f3->get('leaveTo') . '<br>Leave Description:' . $f3->get('leaveDescription') . 'Leave Type:' . $f3->get('leaveType').'<br><br>Hoping for a positive response.<br><br> Thank you.';
}
$mail->Subject = 'Updates on leave date applied';
$mailStatus = (boolean)$mail->send();
if ($mailStatus === true) {
return $mail;
}
} catch (phpmailerException $e) {
$response = array(
'status'=>'error',
'message'=>'Got some error while sending emails',
'exceptions'=>$e->getMessage()
);
return $response;
} catch (Exception $e) {
$response = array(
'status'=>'error',
'message'=>'Got some error while sending emails',
'exceptions'=>$e->getMessage()
);
return $response;
}
}
I received a junk email though [only one] that says :
This sender failed our fraud detection checks and may not be who they appear to be. Learn about spoofing
I cannot figure out what's going wrong.
It is working until previously. And I have tons of emails in my inbox.
Could it be that there's some limit of sending emails?? Or could it be that some one reported it as spam or spoofing??
Any help is very much appreciated. Thanks.

Answer 1

Because you're using SMTPSecure = 'ssl' you won't get any debug output with SMTPDebug = 2 because that only shows SMTP-level output; You need SMTPDebug = 3 to show connection-level problems. This is probably caused by out of date CA certificates in your PHP config. There have been lots of reports of this because gmail changed theirs recently (why your script stopped working). It's covered in the troubleshooting guide.
Also, why are you putting HTML tags in your plan-text AltBody? They won't work in there.
