Question

i have downloaded Swift Mailer from their website and try to send simple email with following code

     <?php
     require_once  lib/swift_required.php ;

    $transport = Swift_SmtpTransport::newInstance( smtp.example.org , 25)
    ->setUsername( your username )
     ->setPassword( your password )
      ;


    $mailer = Swift_Mailer::newInstance($transport);

  //Create a message
  $message = Swift_Message::newInstance( Wonderful Subject )
  ->setFrom(array( john@doe.com  =>  John Doe ))
 ->setTo(array( receiver@domain.org ,  other@domain.org  =>  A name ))
 ->setBody( Here is the message itself )
 ;

 //Send the message
 $result = $mailer->send($message);

?>

once i run the page it gives error

      Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: No such host is known. in E:web_sitesswift_maillibclassesSwiftTransportStreamBuffer.php  on line 233

    Warning: fsockopen() [function.fsockopen]: unable to connect to smtp.anyhost.com:25 (php_network_getaddresses: getaddrinfo failed: No such host is known. ) in E:web_sitesswift_maillibclassesSwiftTransportStreamBuffer.php on line 233

   Fatal error: Uncaught exception  Swift_TransportException  with message  Connection could not be established with host smtp.domain.com [php_network_getaddresses: getaddrinfo failed: No such host is known. #0]  in E:web_sitesswift_maillibclassesSwiftTransportStreamBuffer.php:235 Stack trace: #0 E:web_sitesswift_maillibclassesSwiftTransportStreamBuffer.php(70): Swift_Transport_StreamBuffer->_establishSocketConnection() #1 E:web_sitesswift_maillibclassesSwiftTransportAbstractSmtpTransport.php(101): Swift_Transport_StreamBuffer->initialize(Array) #2 E:web_sitesswift_maillibclassesSwiftMailer.php(74): Swift_Transport_AbstractSmtpTransport->start() #3 E:web_sitesswift_mail	est.php(33): Swift_Mailer->send(Object(Swift_Message)) #4 {main} thrown in E:web_sitesswift_maillibclassesSwiftTransportStreamBuffer.php on line 235

if i remove the line

  $result = $mailer->send($message);

then page execute and no error message display, as soon as i add above line to send email, i got error.

my outgoing server, port and user id & passwords are correct in my file.

Thanks

Answer 1

It s looking for the server smtp.domain.org but isn t able to resolve it.

If you look at the line the last step in the stack trade is calling, you can see it throwing an exception:

if (!$this->_stream = fsockopen($host, $this->_params[ port ], $errno, $errstr, $timeout))
{
  throw new Swift_TransportException(
     Connection could not be established with host   . $this->_params[ host ] .
      [  . $errstr .   #  . $errno .  ] 
    );
}

So you either need to input a valid smtp server or wrap the send() line in a try/catch to catch the exception and either log it somewhere or ignore it

Answer 2

The errors tell you everything you need to know:

getaddrinfo failed: No such host is known.

The specified SMTP server (smtp.domain.org) does not exist, so the mailer script can t connec to it to send the email. At least the domain.org domain DOES exist, so perhaps they ve got the SMTP server named something else:

marc@panic:~$ host -t soa domain.org
domain.org has SOA record ns.domain.org. sales.domain.org. 1267596439 10800 3600 604800 3600
marc@panic:~$ host -t mx domain.org
domain.org mail is handled by 10 mail.domain.org.
marc@panic:~$ host domain.org
domain.org has address 208.109.97.130
domain.org mail is handled by 10 mail.domain.org.

Specify some other SMTP host that DOES exist and try again.

Answer 3

Please control if the port you use is really the port used by your mail server. I have dealt with a similar problem and finally saw that I was using port 25 with yahoo instead of 465.
