R: Header from rewrite

2017-08-12 Thread Lorenzo Petracchi 
I think it is a good idea to prepend a sender: do you know if it is
possibile to prepend a default sender for any sasl user?

I tried smtpd_sender_login_maps and I put a map with addr...@mydomain.com
username: it works for mail from.

This would lose the associated display name, as Postfix has no way to
reconstruct that just from the MAIL FROM.
It might be better to prepend a "Sender:" header on port 587.  Some MUAs
will display "From:  on behalf of " (this is one
of the few actually nice features of Outlook from my perspective).

Otherwise, if you use header-checks to delete the "From:" header, a new one
will be added based on the envelope sender.  You can do this on port 587,
where all and only SASL authenticated users sending outbound email should be
seen.
