Relay access denied

Hello,

How are you ?
I have configured my multiserver by following this link:
http://www.howtoforge.com/perfect-server-opensuse-12.1-x86_64-with-apache2-ispconfig-3
My servers are:
web, mail and db.
ISP config is showing all the servers. I can receive mail but cannot send mail to other domains.
The Squirrel Mail showes the following error:
Message not sent. Transaction failed Server replied: 554 5.7.1 Relay access denied

What should I do to solve it... ?

Thanks in advance.

 

Are there any errors in your mail log (in the /var/log/ directory)?

 

How to see the mail log ?

On SUSE, the mail log is /var/log/mail.

 

Sorry for delay, I was out of town.
By the way, In which server should I run the command, web or mail. Because as you have come to know that I have 3 servers working as a body ...

 

On the mail server.

 

how can I provide SMTP Authentication. I googled the error and found it is because of incorrect SMTP Authentication.

 

Did you provide the correct username/password?

What's in /etc/postfix/main.cf?

 

What am I looking for in this file ? Pls specify me which lines should I concentrate ?

 

Please post the whole file (but please leave out comments).

 

Hi

Does this problem only encounter when using the webmail or also with a client like Outlook?

It may sound "stupid", but did you check your configuration?
Someone on my server had this and I had to tell him 100 of times that he should activate "SMTP needs authentification".

From where I can activate the smtp authentification ?

 

Hi, As we are shifting our office, all our testing servers will be offline for 20 days. I guess I can post the main.cf file after that. Please dont take it otherwise.

Apologies from
