Message Size from network and localhost

[Ing. Davy Leon]

Hi guys

There is a way I currently have a postfix 2.3.3 running. The parameter 

message_size_limit = 1000000

and it's working fine. My question is. There is a way to keep this limits for 
network conections, but stablish a bigger limit or less restrictive limit to 
conections from localhost or own IP ? Lets say 3000000 

Thanks in advance

David
