Swift Mailer vague response code

Have you encountered this error? "Expected response code(s) [250] but got response []"There's no response code at all.I just followed the basic usage of the module. Something like this:\[code\]$email = new Email("Subject");$email->to('[email protected]');$email->message('Message');$email->send('[email protected]');\[/code\]Not sure on the SMTP configuration though.Any solution? Thanks.
