$mailer  = Swift_Mailer::newInstance($transporter);
$message = Swift_Message::newInstance('Portfolio Enquiry')
    ->setFrom(array('ayrshireminiscontact@gmail.com' => 'CRMPicco Portfolio Enquiry'))
    ->setTo(array('picco@crmpicco.co.uk' => 'A name'))

我尝试了 http://www.google.com/accounts/DisplayUnlockCaptcha 和我可以通过网络浏览器登录到该帐户，而不会出现任何问题.

I have tried http://www.google.com/accounts/DisplayUnlockCaptcha and I can log in to the account through a web browser without any problems.

这发生在我的本地开发机器和公众可访问的站点上.这是我的GMail帐户或我的实施问题吗?

This happens on my local development machine and the publically-accesible site. Is this an issue with my GMail account or my implementation?
