Laravel-why admin receives every email message? - email

Question

I am working on a web application with multiple users, and I have some issue with sending emails.
Sending is working fine, no problems, but the issue is that every mail interaction between visitors and users is sent to admin email address stated in env file. I am using gmail for sending, Laravel 8.
For example, visitor A has sent a message to user B. User B received mail correctly, but also admin received message.
Thanks for help.
Here is my EmailsController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Mail;
class EmailsController extends Controller
{
public function send(Request $request)
{
function sentence_case($string) {
$sentences = explode(" ",$string);
$sentences = array_reverse($sentences);
$new_string = '';
foreach ($sentences as $key => $sentence) {
$new_string = ucfirst(mb_strtolower(trim($sentence)))." ".$new_string;
}
return $new_string;
}
$this->validate($request, [
'ime' => 'required', //visitor name
'email' => 'required', // visitor email address
'poruka' => 'required' //visitor message
]);
$ime = $request->get('ime');
$ime = sentence_case($ime);
$email = $request->get('email');
$poruka = $request->get('poruka');
Mail::send('emails.message', [
'name' => $ime,
'email' => $email,
'comment' => $poruka ],
function ($m) use ($email) {
$m->from($email);
$m->to('usersemail#yahoo.com', 'MyApp')
->subject('Website Contact Form');
});
/* usersemail#yahoo.com is registered user email address different from aplication admin/owner email addres stated in env file, but admin receives this message */
if (Mail::failures()) {
return response()->Fail('Sorry! Please try again latter');
}else{
return back()->with('success', 'Thanks for contacting me, I will get back to you soon!');
}
}
}
