Answer 1

I had the same error: Connection could not be established with host smtp.gmail.com [ #0] and followed the steps outlined here: https://github.com/swiftmailer/swiftmailer/issues/544.

Try adding the following lines to _establishSocketConnection() in Swift/Transport/StreamBuffer.php on line 263:

$options['ssl']['verify_peer'] = FALSE;
$options['ssl']['verify_peer_name'] = FALSE;

Note that this is not a perfect solution as it involves: a) Hacking core code which may be overwritten in a SwiftMailer update, and b) decreases the security of your app as you're no longer validating the connection. But as a temporary work-around it worked for me.

Answer 2

This one line change in .env file will make it work

MAIL_DRIVER=sendmail

If it also has no effect try to switch between the mail port

MAIL_PORT=587

Or

MAIL_PORT=465

This will work only if you enable "Allow Less secure app access" under google account

Answer 3

this worked for me after a long search time, the best configuration :

'driver' => 'smtp',
'host' => 'smtp-mail.outlook.com',
'port' => 587, ( or 25)
'encryption' => 'tls',

Answer 4

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=test@gmail.com
MAIL_PASSWORD=testpassword

Answer 5

In your .env file you will need to set the email address and password of your email account:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=test@gmail.com
MAIL_PASSWORD=testpassword

and in mail.php

<?php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
    'port' => env('MAIL_PORT', 587),
    'from' => ['address' => 'yourEmail@gmail.com', 'name' => 'Your Title'],
    'encryption' => 'tls',
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,
];

and clear the config cache with:

php artisan config:cache
