However, the LMTP session can authorize each message as a particular 
sender as well.  So while the postfix server authenticates to the LMTP 
server as "postfix" or whatever, the postfix server is then trusted to be 
correct when it says "this message sent by xyz".

In that case, you can use SMTP Auth to your postfix server to submit the 
message, which then relays the authentication info for the message.

This is a how to go about implementing restricted post shared folders.
