Hello all, Anyone knows how to eliminate duplicated messages in postfix? Let me explain better: i have a email user@ and a alias all@ that send a copy of the messages to user@ - when someone send to user@ and all@ in the same message i will receive duplicated. I know this is the right thing, but my boss dont want receive duplicated messages anymore... I'm using ispconfig 188.8.131.52 with currier. thanks!
