Mr. C. · 08-01-2008, 01:18 AM

I make no recommendations on HowTo's in general, but here's one you can try out::

Hi all,
i managed to set up the server and all the neccessary services are running. problem is with postfix again, after following the document at

Quote:

http://www.howtoforge.com/perfect-server-opensuse11

i still encountered th e same issues.
First of all i set the hostname of the machine to nelly, and the domain to mail1.local
All these configs are also correctly defined in the /etc/postfix/main.cf.
-The users are able to login thru squirrelmail
-They are able to compose mail, and send to other users configured on the machine, but the mail is not delivered to the recipients inbox, this is the log generated i the process

Im so confused coz the log shows something like sam@suse.de,just 2 mention, sam is a username i created on the system, but where does the @suse.de domain come from?

Secondly, when sam sends mail to domains like yahoo, G-mail etc, they are delivered only that it shows the mail is from sam@suse.de, im so confused by this suse.de thing, the relay in the log indicates mx1.suse.de, can anyone help me here coz im so lost and confused.

Thnx

Again, post your postconf -n output.

It really, really, really is best to get things working one step at a time (eg. postfix w/o TLS/AUTH, AUTH standalone, and then combine).

Mr. C. · 08-02-2008, 02:42 AM

What version of postfix was installed?

The parameter check_relay_domains at the end of smtpd_recipient_restrictions was deprecated back in 2002-12-02.

This is one of the reasons why I generally do not give pointers to HowTo's - so many are wrong, or dated.

madfed · 08-03-2008, 11:47 PM

Version of postfix installed:-

Quote:

nelly:~ # rpm -q postfix
postfix-2.5.1-28.1

Do you think its the postfix with the problem or the configs?
Thanx

Mr. C. · 08-03-2008, 11:53 PM

I'd suggest you start with the default postfix config file, and work from there. If you want to do this, move the existing main.cf file elsewhere, and reinstall postfix to get the standard config (or at least the one that is used with your distro). Then post the output of postconf -n again.

I un-installed the postfix and reinstalled fresh one and changed a few parameters as shown in the output above,

billymayday · 08-04-2008, 07:17 AM

So what is happening? It it working?

madfed · 08-04-2008, 09:13 AM

Nope,
same issue, user can login and compose mail but its not delivered to recipients Inbox, and also weired domains showing up the logs.

I didnt configure my domain as suse.de, but as u see in the log there appears sam@suse.de, nelly@suse.de; as for sam & nelly, they are configured users on the Server but where does the suse.de come in from. actually my configured domain is mail1.local.
Im totally lost!

First setup postfix and then setup dovecot.

Postfix howto:
http://www.postfix.org/docs.html

Dovecot howto:
http://wiki.dovecot.org/FrontPage

Setup the most basic postfix: just local user mail. Then slowly adapt to allow external mail and out-going mail.

Take baby steps. I also would recommend a VERY good book called: The Book of Postfix - State of the art message transport, by Ralf Hildebrandt and Patrick Koetter. ISBN: 978-1-59327-001-8
I'm reading it now. It will tell you everything you need to know about postfix. I haven't read other books on postfix, but this seems to get it all.

billymayday · 08-04-2008, 03:48 PM

What is the exact command you are using to send mail, or if from a client, what address are you sending to?

What is the content of /etc/hosts?

Do you have a line similar to

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

in main.cf?

Can your try

echo "hello" | mail -s test1 nelly

echo "hello" | mail -s test2 nelly@mail1.local

and

echo "hello" | mail -s test3 nelly@nelly.mail1.local

and show the logs around these

You've got something strange on your system

I tried the above n the first command delivers mail to nelly's inbox and it shows that its from root@nelly.mail1.local
Second command has its mail bounced.
Third command also delivers mail to nelly Inbox

Now that means i have to send mail to user@nelly.mail1.local, for mail to be delivered to the users inbox. but then it shows the mail is from user@suse.de, thats kinna weired coz i thought it wud show that its from user@nelly.mail1.local, isn't it? i dont knw where the suse.de is coming from.
For example i login as sam and send mail to editorail@nelly.mail1.local, the mail is delivered but then it shows its from sam@suse.de.

billymayday · 08-05-2008, 02:07 AM

What is the hostname of your machine (type hostname from command prompt)

Edit - and what's in /etc/hosts?
