GMail Username and Password not accepted error when sending email with SwiftMailer

问题

I get the following error when trying to use my GMail account to send an email from my PHP application with SwiftMailer.

535-5.7.8 Username and Password not accepted

This is my SwiftMailer code:

$transporter = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
    ->setUsername('ayrshireminiscontact@gmail.com')
    ->setPassword('~password-in-here~');

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

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

This is the entry in my Apache error log and the stack trace.

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

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

回答1:

You need to allow access from less-secure apps, because IMAP via password is fundamentally insecure. (it's non-revocable)

Better yet, switch to OAuth authentication.
