Producent oprogramowania FortiNet opublikował aktualizacje dla FortiMail o oznaczeniu 6.0.11. W nowszej wersji poprawiono profile ochronne, takie jak antyspamowy i antywirusowy. Główne naprawy dotyczyły problemów z skanowaniem plików PDF, zarówno problem dotyczący linków URL, zostały skorygowany. Po aktualizacji, możemy również zauważyć poprawę działania poczty e-mail, naprawiono problemy z logowaniem, jak i trudności z załączaniem plików graficznych w wiadomościach. Dzięki wersji 6.0.11, udało się zoptymalizować zużycie procesora, gdyż problem dotyczył błędnego działania procesu ,,mailfilterd”.
