What is the proper way to deal with non-existing e-mail addresses?

When somebody emails to a non-existing e-mail address postfix bounces these by default with a "Recipient address rejected: User unknown in local recipient" error. I wonder what the appropriate behavior is. To discard emails for unknow, users, forward them to another address or bounce them? What abo

A question about mynetworks

I've added my local ip adress range to allow computers in my lan to send e-mails though my local postfix server. Is this the correct setting to achieve this? And am I correct that with the current mynetworks configuration only clients in my lan can user the smtp server? According to mxtoolbox I d
