Hi all,

I am installing postfix from https://help.ubuntu.com/community/Po...efault%20setup and i am stuck at "Test your default setup" I am not able to telnet localhost 25, the error is telnet localhost 25
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

This worked immediately after i installed mailx. But, after a reboot the telnet just doesnt work. how can i test the default postfix setup. Also, is there way to remove the default sendmail attached to each user account. Because, sendmail was installed on this machine and i guess sendmail is the default mail service for each user account?

Thanks

Sendmail isn't attached to a user account. You can uninstall the sendmail package if you want.

Is postfix running ?

ps -elf | grep postfix

Is postfix listening on all interfaces?

netstat -anl --tcp | grep 25

Is a iptables blocking the port?

iptables -L

Hi,

Is postfix running ?
NO! I am not able to start the service also, if i execute /etc/init.d/postfix start, i don't get any message, the prompt comes back.


How do i get this started?

netstat -anl --tcp | grep 25
No its not listening!

Is a iptables blocking the port?
The output of iptables -L

root@servername:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Look in /var/log/messages and /var/log/mail* for any messages related to the attempt to start postfix. Post those.

Ok, i figured out that smtp was not installed (a package called apcaccess), after installing this i can atleast telnet to localhost. But, here's what is happening.

root@ns1:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
sendmail: fatal: open /etc/postfix/main.cf: No such file or directory
Connection closed by foreign host.

How do i solve this, i want to test this before i go ahead with the postfix installation.

Thanks!

You are using postfix, but do not have postfix's critical "main.cf" parameter configuration file. How did you install postfix?

It doesn't make sense to attempt to test postfix before you install postfix. Install postfix, and then test telnet localhost 25.

I am installing Postfix from the link https://help.ubuntu.com/community/Po...efault%20setup

and the first step in this page is to install Postfix and mailx unless the apt-get install is meant for something else!!

Install Postfix

In this setup I assume that your domain is yourdomain.com and it has a valid MX record call mail.yourdomain.com. Remember to replace yourdomain.com with your actual domain in the example codes in this howto. Also I assume that you know what an MX record is. To find out MX your type in a terminal:

dig mx yourdomain.com

To install postfix

sudo apt-get install postfix

Intall mailx package for use as command mail utility program. Mail command is installed with this package.

sudo apt-get install mailx

And for sure postfix is installed on my machine as i did it myself.

Do you have a Sendmail installed and configured also ?

Postfix will not output the line in bold:

when you telnet to port 25. Postfix's sendmail compatibility binary is not used in this situation.

So this seems to leave one to believe your you have two MTAs installed. Perhaps the alternatives/mta setup is incorrect (more about this here: http://87.249.105.167/mirror/linuxtr...l/LiB0159.html).
