无法使用SwiftMailer发送电子邮件

Question

I am trying to send email, with the following php code, using SwiftMailer.

$transport = Swift_SmtpTransport::newInstance('smtp.domain.com', 25);
$transport->setUsername(getenv('USER_NAME'));
$transport->setPassword(getenv('PASSWORD'));
$swift = Swift_Mailer::newInstance($transport);

$mail = Swift_Message::newInstance();
$mail->setSubject('Hello');
$mail->setFrom(array('sender@domain.com' => 'Sender Name' ));
$mail->setTo(array('receiver@domain.com' => 'Receiver Name'));
$mail->setBody('some message');

$result = $swift->send($mail, $failures);

if ($result)
{
    echo "Message successfully sent!";
}
else
{
    echo "There was an error:\n";
    print_r($failures);
}

the following error is coming ...

There was an error:

Array ( [0] => receiver@domain.com )

I am using Mandrill as SMTP ...

Answer 1

Make sure you use real email addresses instead of receiver@domain.com and sender@domain.com.

Another thing - you may need to set SMTP server, username and password in order to send emails from your server.

Answer 2

If the variable name does not yet exist, it will be initialized as an empty array and then failures will be added to that array. If the variable already exists it will be type-cast to an array and failures will be added to it.
