Swift_TransportException in Laravel 5.2 mail sending

Question

I am trying to send mail for my laravel app from a gmail account with Allow less secure apps: ON and 2-Step Verification OFF

.env part for mail:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=********
MAIL_ENCRYPTION=ssl

config/mail.php:

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => '[email protected]', 'name' => 'Admin'],
'encryption' => env('MAIL_ENCRYPTION', 'ssl'),
'username' => env('[email protected]'),
'password' => env('********'),
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => env('MAIL_PRETEND', false),

First I tried using 'encryption' => env('MAIL_ENCRYPTION','tls'). But got the following error message:

ERROR: exception 'Swift_TransportException' with message 'Expected
response code 250 but got code "530", with message "530-5.5.1
Authentication Required. Learn more at 
530 5.5.1  https://support.google.com/mail/answer/14257  
z3sm16020712par.17 - gsmtp"' in
/home/shafi/Projects/Lib/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:383

I visited https://support.google.com/mail/answer/14257 and found everything is at the recommended state.

After this I used 'encryption' => env('MAIL_ENCRYPTION','ssl') but this time the same ERROR.

What should I do to fix the error? What am I missing?

Step 1: Revert your config/mail.php to original file. The config/mail.php should look like this

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => '[email protected]', 'name' => 'Admin'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'sendmail' => '/usr/sbin/sendmail -bs',

Step 2: The .env file should be like

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=whateverisyourpassword
MAIL_ENCRYPTION=ssl

Port is 465 and not 587

Step 3: Test the below code by pasting in appropriate controller function

\Mail::raw('This is an test e-mail', function ($message) {
    $message->to("[email protected]", "someone");
    $message->subject("hi checking");
    $message->getSwiftMessage();
});

P.S: Never ever forget to stop and then again start the server by using php artisan serve every time if some change is made to .env file. If not then you may be sucked into The Labyrinth of Time.

Solution 2

Visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If asked, enter the letters in the distorted picture.

Note: If this still didn't help then retry the process couple of more times and wait then try to send the email from your Laravel apps. This should resolve the issue.

Your code is fine. However, Gmail is not allowing your Laravel apps to log in to your Gmail account which is why you're experiencing the issue. In this case, please also ensure that you've allowed your Laravel apps from your Gmail account activity options and also try changing few settings from the allow less secure apps access options.

How to allow Laravel apps from Gmail account? I tried to do, but couldn't.

[Shafi]

Appreciate your effort.I tried, but got the same error.

Are you sure you haven't missed anything? I test ran the above code in laravel 5.2 with two different gmail accounts and it's working.

[Shafi]

Can you share your project repository or files related to sending mail?

[Shafi]

No. Tried in multiple way but ends with same error.

[curious_coder]

Try to provide your code to new set of eyes. Maybe they can find what you missed out

[Shafi]

I think I am doing everything okay as I did this before. I will try again when it's time to deploy my work on server. Till then I will work with pretend: true. Thanks for your care about this.

[Shafi]

btw, I do not think the port should be different in .env and mail.php.

First preference is given to variable found in .env . if the variable is not found then default value is taken
