I want to sent emails from my localhost with laravel 5.4. It is showing me the following error: screenshot of the error

This is my .env file

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=mypassword
MAIL_ENCRYPTION=tfl

This is my mail.php file

<?php

This is my mail class in App\mail\ directory

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class CompanyVerificationEmails extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->view('emails.comp_ver_emails');
    }
}

This is my controller

<?php

namespace App\Http\Controllers;

use App\General_model;

use App\Http\Requests;

use Session;

use Mail;
use App\Mail\CompanyVerificationEmails;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller;

use Illuminate\Foundation\Validation\ValidatesRequests;

use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

use Illuminate\Foundation\Auth\Access\AuthorizesResources;


class General_controller extends Controller
{

public function sentemail()
{
     $mail_to = '[email protected]';

     Mail::to($mail_to)->send(new CompanyVerificationEmails);

     dd('Mail send successfully');
}

}

Solution

I had this issue too, this is how i fixed it. Though it is not advisable to change vendor files but this fix worked and it enable me to send mail from my localhost.

1. Locate StreamBuffer in your vendor folder. It should be in this location

C:\xampp\htdocs\mylaravel\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport

2. Open the file StreamBuffer.php
3. Find this method _establishSocketConnection
4. Add this as shown below

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

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

    private function _establishSocketConnection(){
       ....

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

       $streamContext = stream_context_create($options);
       $this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, $streamContext);

    .... }

It's like the ssl keeps preventing the mail from been sent. I hope this helps
