This is my setup:

ArchLinux box
Postfix, setup with smtp relay as described here / (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 instead of 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 using my personal Gmail account, and that works too.

I think tour Postfix is already sending your mails with the right from address. GMail is probably rewriting the from address to your GMail address.

It might work if you add the desired from address as a "send mail as" email address in your GMail account settings.

But i have several users on that computer... user1, user2, user3, and I can only set one address as "sand as" – Kaurin Mar 7 '12 at 22:49
Ok, now i'm pretty sure postfix is doing this. I have set "send mail as" and i still get the gmail address as the reply address. – Kaurin Mar 8 '12 at 16:42
Strange, I assume you verified the send as and all? You should check what's going on in the log, probably /var/mail.log. To see the complete smtp conversation between postfix and, increase postfix smtp verbosity by adding a -v behind the smtp unix - - - - - smtp line in /etc/postfix/ (Doc) – J3L2404 Mar 8 '12 at 18:11
i have added the -v. here is the pastebin – Kaurin Mar 8 '12 at 19:26
