Expected response code 220 but got code “”, with m

Question

I am using Laravel Mail function to send email. The following is my app/config/mail.php file settings.

'driver' => 'sendmail',
'host' => 'smtp.gmail.com',
'port' => 587,
'from' => array('address' => '[e-mail]', 'name' => 'MyName'),
'encryption' => 'tls',
'username' => 'myUsername',
'password' => "password",
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => false,

Controller Mail Method

//Send Mail     
Mail::send('sendMail', array('key' => 'value'), function($message)
{
    $message->to('[e-mail]', 'Sender Name')->subject('Welcome!');
});

When I run the code it gives me following error message:

Swift_TransportException

Expected response code 220 but got code "", with message ""

I have created a SendMail.php file in view which contains some data.

How do I resolve this error message?

Answer 1

For me the problem was the port. I first incorrectly used port 465, which works for SSL but not TLS. So the key thing was changing the port to 587.

Answer 2

What helped me... changing sendmail parameters from -bs to -t.

'sendmail' => '/your/sendmail/path -t',

Answer 3

I did as per sid saying my env after updating is

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<mygmailaddress>
MAIL_PASSWORD=<gmailpassword>
MAIL_ENCRYPTION=tls

this did work without 2 step verification. with 2 step verification enabled it did not work for me.

Answer 4

This problem can generally occur when you do not enable two step verification for the gmail account (which can be done here) you are using to send an email. So first, enable two step verification, you can find plenty of resources for enabling two step verification. After you enable it, then you have to create an app password. And use the app password in your .env file. When you are done with it, your .env file will look something like.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>
MAIL_ENCRYPTION=tls

and your mail.php

<?php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.gmail.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => ['address' => '<<your email>>', 'name' => '<<any name>>'],
    'encryption' => env('MAIL_ENCRYPTION', 'tls'),
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,

];

After doing so, run php artisan config:cache and php artisan config:clear, then check, email should work.

Answer 5

In my case I had to set the

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465           <<<<<<<------------------------- (FOCUS THIS)
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>

MAIL_ENCRYPTION= ssl    <<<<<<<------------------------- (FOCUS THIS)

to work it.. Might be useful. Rest of the code was same as @Sid said.

And I think that editing both environment file and app/config/mail.php is unnecessary. Just use one method.

Edit as per the comment by @Zan

If you need to enable tls protection use following settings.

MAIL_PORT=587
MAIL_ENCRYPTION= tls  

See here for some other gmail settings

Answer 6

if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.

EXAMPLE CODE:

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
  ->setUsername([e-mail])
  ->setPassword(password)
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('News Letter Subscription'))
  ->setFrom(['[e-mail]' => 'A Name'])
  ->setTo(['[e-mail]' => 'A Name'])
  ->setBody('your message body')
  ;

// Send the message
$result = $mailer->send($message);
