Zend Mail keeps giving me a Socket Error - zend-framework

Question

I'm having trouble with sending email using the zend framework. I keep getting a "Could not open socket" error.
I don't know whats wrong here - it used to work on my other host. Ever since I shifted it to another host I can't send emails. I've set up the configuration values to match the new email server.
Heres my code:
$config = array('auth' => _config('mail', 'auth'),
'username' => _config('mail', 'email'),
'password' => _config('mail', 'password'));
$tr = new Zend_Mail_Transport_Smtp(_config('mail', 'smtp'), $config);
$mail = new Zend_Mail();
$mail->setDefaultTransport($tr);
$mail->setFrom(_config('mail','email'), _config('mail','name'));
$mail->addTo($account_email);
$mail->setSubject($mailTitle);
$mail->setBodyText($mailContent);
$mail->send($tr);
EDIt ===
Well the code posted above is my actual code - I don't know whats wrong with it as it used to work on another host.
The following is the exact error I'm getting

marhaba Ali! ,
digging the code of Zend mail shows http://framework.zend.com/svn/framework/standard/trunk/library/Zend/Mail/Protocol/Abstract.php
protected function _connect($remote)
{
$errorNum = 0;
$errorStr = '';
// open connection
$this->_socket = #stream_socket_client($remote, $errorNum, $errorStr, self::TIMEOUT_CONNECTION);
if ($this->_socket === false) {
if ($errorNum == 0) {
$errorStr = 'Could not open socket';
}
/**
* #see Zend_Mail_Protocol_Exception
*/
require_once 'Zend/Mail/Protocol/Exception.php';
throw new Zend_Mail_Protocol_Exception($errorStr);
}
if (($result = $this->_setStreamTimeout(self::TIMEOUT_CONNECTION)) === false) {
/**
* #see Zend_Mail_Protocol_Exception
*/
require_once 'Zend/Mail/Protocol/Exception.php';
throw new Zend_Mail_Protocol_Exception('Could not set stream timeout');
}
return $result;
}
and usually the error number 0 because of
if ($errorNum == 0) {
$errorStr = 'Could not open socket';
}
from : http://php.net/manual/en/function.stream-socket-client.php
On failure the errno and errstr
arguments will be populated with the
actual system level error that
occurred in the system-level connect()
call. If the value returned in errno
is 0 and the function returned FALSE,
it is an indication that the error
occurred before the connect() call.
This is most likely due to a problem
initializing the socket. Note that the
errno and errstr arguments will always
be passed by reference.
I guess its some firewall blocking the connection to be sent out ,
system-level or network-level error
If you update your answer with more detailed info , i would be happy to help
