This code working fine on local server. But when i tried to in godaddy server i saw the following Error :

.env (mail part)

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=tls

Mail.php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.gmail.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => [
    'address' => env('MAIL_FROM_ADDRESS', '[email protected]'),
    'name' => env('MAIL_FROM_NAME', 'xxxx'),
    ],


    'encryption' => env('MAIL_ENCRYPTION', 'TLS'),
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,

What should I do now?

This is an old thread, but my resolution was a bit different for the same error. Turns out my Swift configuration is fine. The IP from my server was blocked by Google as suspicious. I was able to clear it by visiting this link, then executing my mailer code from the server. http://www.google.com/accounts/DisplayUnlockCaptcha

Sorry, I know this is an old thread but i came across a similar issue with GoDaddy SMTP with the Laravel application running on AWS EC2. The below code works for me maybe it will help you guys too.

MAIL_DRIVER=smtp
MAIL_HOST="relay-hosting.secureserver.net"
MAIL_PORT=25
MAIL_USERNAME="<[email protected]>"
MAIL_PASSWORD="<your_password>"
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME="${APP_NAME}"
MAIL_FROM_ADDRESS="<[email protected]>"
