Well, maybe OT but nevertheless:

The tor exit notice can be improved. I derived a good example from the WIKI and adapted it just a little bit for Germany: http://5.9.158.75/

And a second thing: If you close port 465, then you should close 587 as well IMO.
FWIW I do fine with just closing port 25 and :
ExitPolicy reject 217.69.139.160:465        # smtp.mail.ru
ExitPolicy reject 94.100.180.160:465        # "
ExitPolicy reject [2a00:1148:db00::8]:465   # "
b/c the admins there requested it.
