1) Where is your Postfix conf, one can comment on?

2) The message-id is empty or absent, did you _verified_, that the message 
contains "From" and "Date" headers at all? I guess it does not contain 
them either.
So, no client can display missing information.
Postfix's "from" is the envelope from, that is storred in the Return-Path 
header in the message the client retrieves.
