Sorry for flooding I forgot also this:


ExitPolicy reject *:25
ExitPolicy reject *:6660-6669
Exitpolicy reject 217.78.206.0/24:*
Exitpolicy reject 62.241.240.0/24:*
Exitpolicy reject 62.197.172.0/24:*
Exitpolicy reject 192.168.0.0/16:*
Exitpolicy reject 10.0.0.0/8:*
ExitPolicy accept *:*

With my old exit policy (above)  I didn't get any warnings.
