postfix rewrite headers

my mail is being rejected from remote smtp servers since they can't verify my domain name enclosed in the mail headers.

"Sender address rejected: Domain not found "

heres an envelop:

PHP:

-
X-Original-To: me@mixhacks.com
Delivered-To: me@mixhacks.com
Date: Wed, 14 Nov 2007 00:25:57 -0600
From: root <root@linux-server.robust>
To: me@mixhacks.com
Subject: root to me
User-Agent: Mutt/1.5.16 (2007-06-09)



since i'm using an account on my box to send email I am getting
root@`hostname -f`

i changed my hostname to mixhacks.com but the old hostname must be in the config somewhere.

postconf | grep robust
reveals nothing.

postfix stop
postfix start
postfix reload

doesn't update the hostname attached to root account when mailing.

1)

how can i map a user to a specific domain?

meaning root user sends:
[email protected]
me user is sent as:
[email protected]

PHP:


linux-server:/var/spool/mail # postconf | grep my
append_at_myorigin = yes
append_dot_mydomain = yes
lmtp_lhlo_name = $myhostname

smtpd_proxy_ehlo = $myhostname
smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination


 

Which distribution are you using?

 

opensuse 10.3

I am using opensuse 10.3

i finally can receive emails from external sources.

i just haven't figured out how to rewrite the envelop so that it uses a real domain instead of my old hostname.
until i do that i can't send as i'm seen as a spammer since domain cannot be resolved.

You can change the hostname in YaST. Just run

Code:

yast

to start it.

 

yup

yeah i've already done that.

but postfix still uses linux-server.robust
i've grep postconf | grep robust
and don't see anything.

i'm thinking the problem is with
postfix masquerading

the from address on outbound email keep [email protected]st
also the email id generated is timestamp.linux-server.robust

so close but yet so far away.


today i'm going generate an email from an external client and see if it will rewrite correctly.. to bad i can't fix this locally.

with all these postfix tutorials.. wished there was just a simple virtual hosting with flat files non db.

 

What's the output of

Code:

telnet localhost 25

?

 

wasted several days

ha i learned a lot about postfix in these last few days..

problem was my mutt mail client.

instead of using a client .. i should have kept it all within postfix:
#sendmail -v [email protected]
#sendmail -v [email protected]

postfix was already setup fine...it doesn't generate
linux-server.robust


mutt client has a from field you can set:
ESC f allows you to edit the from: field
on per message basis

you can set it statically in
vi /home/username/.muttrc
my_hdr FROM:Leblanc Meneses <[email protected]>
... wonder how you add multiple domain support ... [email protected]?

i still don't know how set the message-id which still appends linux-server.robust

but at least i know what the real problem is.

anyways thanks everyone.
