This is my setup:
Postfix, setup with smtp relay as described here / email@example.com (example, not actual. read on) Dynamic DSL IP from my ISP
DynDNS account / ddclient to refresh my IP
This setup works fine. I can send mail from my local accounts from my ArchLinux box to the outside world.
However: I would like the "From" email address to show firstname.lastname@example.org instead of email@example.com so I can reply directly to my box, instead to that Gmail account I don't even check.
Is this possible with postfix?
P.S. I don't want to forward mails from Gmail :)
P.P.S. I have already tried sending directly to firstname.lastname@example.org using my personal Gmail account, and that works too.
