How to send an email using SwiftMailer in Laravel 5.7?

Question

Laravel

Good afternoon,
Has anyone encountered such a problem when sending mail?
Swift_TransportException (503)
Expected response code 354 but got code "503", with message "503 Valid RCPT command must precede DATA
"

try {
       $this->mailer->to($user->email)->send(new VerifyMail($user)); 
} catch (\DomainException $e) {
      Log::warning('Email sending not supported on local');
 }

Tell me please - how to fix it?
