SuSE

Hi All,

I have a system running with Suse Enterprise Linux 9.0.

xyz# uname -a
Linux xyz 2.4.21-291-smp #1 SMP Tue May 24 14:07:45 UTC 2005 i686 unknown

I would like to configure postfix on this system for sending mails as a root user using "mail" command to smtp server (Windows System) which will then forward it to the correct address.

Example " xyz# mail xyz@yahoo.com "

As per my knowledge there are two main configuration files in /etc/postfix folder;

main.cf
master.cf

Can anyone help me out what setting needs to be done for sending the mails to my smtp server from SuSE system.

Note : I have added the entry for my smtp server in /etc/hosts file.

Note : I have check the telnet connection using port 25 for the smtp server, it works fine.

Thanks & Regards,
jumadhiya.

You can get good documentation, including standard configuration examples, from the Postfix.org site.

Thanks zazzybob...!!!

But after doing the configuration by following the web link given by you, I am facing the problem while sending mails from my SuSE Linux box.

Error from /var/log/mail file:

When I send mail using “mail” command, it takes “.” from myorigin = $smtp.xyz.com entry of main.cf file.

If I change myorigin to myorigin = $smtp@xyz.com, in the output of mail log file, from address will be
from=<root@@xyz.com>.

Entries from /etc/postfix/main.cf file :

#myorigin = $myhostname
myorigin = $smtp.xyz.com

mynetworks = 127.0.0.0/8 10.10.20.206/24
#mynetworks = $config_directory/mynetworks
#mynetworks = hash:/etc/postfix/network_table

relayhost = $smtp.xyz.com
#relayhost = gateway.my.domain
#relayhost = uucphost
#relayhost = [an.ip.add.ress]

#mydestination = $myhostname, localhost.$mydomain
mydestination = $cn2, localhost.$smtp.xyz.com $smtp.xyz.com
#mydestination = $myhostname, localhost.$mydomain, $mydomain,

Can anyone please help me out to resolve this issue...!!!

Thanks & Regards,

This:

root@.xyz.com

is a badly formed address.

Try changing your "myorigin" directive to

myorigin = smtp.xyz.com

i.e. remove the '$', then issue

postfix reload

When I changed ;

myorigin = smtp.xyz.com

As per the above outputs, can you tell me which one should I use. My smtp server address is like abc@xyz.com.....but not like abc@smtp.xyz.com.

Now I just need to add user "root@xyz.com" on my smtp server (Windows) for sending the messages from my SuSE Linux box using root id...right...??

Correct me if I am wrong at any place.

Thanks & Regards,

Looks like the SMTP server you're relaying to is rejecting the sender address - maybe you have UBE controls or blacklists or something like that (I don't know MS Exchange so wouldn't know what to suggest here) - with Postfix you can have DNSRBLs, access maps, sender restrictions, etc to govern this.

Try

Code:

$ telnet the.windows.smtp.server 25
HELO xyz.com
MAIL FROM: <root@xyz.com>
RCPT TO: <someone@xyz.com>
DATA
Subject: Testing mail
Hello,
This is a test
.
QUIT

i.e. enter the SMTP commands manually, does this work? Does the sender address still get rejected?
