A side remark: I never exclude local servers completely - what if one of 
these gets hacked and start sending out spam? You would not  even notice 
it before your upstream  Mail server starts to block your requests. I 
just give these machines a negative score that ensures passthrough of 
normal or even slightly spammy mail but would detect blatant bot-like spam.
This would also solve your problem with mynetworks as you just declare 
the networks you want to exclude without a connection to postfix
