I just stood up a super vanilla postfix email server. Right now I have
just a few lines modified in /etc/postfix/main.cf to get email working
however when I send email, it is received as the following:

X-Original-To: carlos
Delivered-To: car...@email.foo.com
To: car...@email.foo.com
Subject: Email Server is up!
Date: Tue, 15 Jan 2008 08:01:32 -0500 (EST)
From: r...@email.foo.com (root)

How and where would I adjust this so email is simply received as
normal like:

car...@foo.com rather car...@email.foo.com?

Is this in the main.cf?

myhostname, mydomain and myorigin is probably what your looking for from the main.cf file.

I have the following line under "mydestination"

Is that wrong? What should it read or is it out of order?

agreed. sounds like you didnt edit quite enough. there's lots of documentation.. but just look through the file.. it is easy enough.

hm.. i dont think that is the right place. what about mydomain?

mydomain = foo.com

my orgin = $mydomain

Is this not the correct thing?

Grrrr - obviously I am unable to spell "myorigin" correctly. Duh!

Thanks all. I got this now working.
