Postfix relay host from address configuration
I have created a postfix email server in Ubuntu 9.04
I have set my relay host to smtp.gmail.com
I have come to know from web sources that I need to use sasl_passwd file where I need to mention both gmail ID and password for authentication.
but because of this all my three users using postfix are able to send their emails using same from address
Now what happens is that I get all the reply emails in one gmail account from where I can download them using fetchmail but how to seperate them to send them to different users.
Or in other way can I send emails using different from address or at-least different reply-to address.
so that when recipients reply to those email I get them in different gmail accounts from where I can get them to different users folders on my server.
your help will be highly appreciated.
Thanks in advance
