Laravel 6 ForgotPasswortController doesn't send reset emails

I'm debugging a Laravel 6 application which isn't sending password reset emails to the users. All other emails send by the application work fine and I've tried a different mailserver without success. The applications doesn't throw any errors in the logs and returns that the reset email was send successfully, if a valid email address was entered.

The reset emails should be send by the default ForgotPasswordController. Only the methods sendResetLinkResponse and sendResetLinkFailedResponse were modified to some custom JSON response.

class ForgotPasswordController extends Controller
{
    use SendsPasswordResetEmails;

    protected function sendResetLinkResponse(Request $request, $response)
    {
        return response()->json([...], 200);
    }

    protected function sendResetLinkFailedResponse(Request $request, $response)
    {
        return response()->json([...], 422);
    }
}

The endpoint calls the sendResetLinkEmail function, definied in the SendsPasswortResetEmails trait.

/**
 * Send a reset link to the given user.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\RedirectResponse|\Illuminate\Http\JsonResponse
 */
public function sendResetLinkEmail(Request $request)
{
    $this->validateEmail($request);

    // We will send the password reset link to this user. Once we have attempted
    // to send the link, we will examine the response then see the message we
    // need to show to the user. Finally, we'll send out a proper response.
    $response = $this->broker()->sendResetLink(
        $this->credentials($request)
    );

    return $response == Password::RESET_LINK_SENT
                ? $this->sendResetLinkResponse($request, $response)
                : $this->sendResetLinkFailedResponse($request, $response);
}

This functions behaves like expected, with a valid email address the overwritten sendResetLinkResponse method is called. Also entries in the database table password_resets are generated.

The User model has the CanResetPasswordContract and the CanResetPassword trait, like described in the documentation: https://laravel.com/docs/6.x/passwords. Also the email column on the User model and in the database is called just email.

I've read in another post that MAIL_FROM attributes in the .env could cause some problems, but I think that`s not the problem in my case also because all other emails that are send by the application work fine.

MAIL_FROM_ADDRESS=email@test.com
MAIL_FROM_NAME="My Application"

I hope you can point me in the right direction to track down the issue. Thank you!
