I'm a newbie, so I hope I'm asking my question in a manner respectful of this forum and in a sufficiently informative way.

I've set up my Linode using Ubuntu 10.04 LTS and the WordPress StackScript at revision 146.

My Linode is at li589-228.members.linode.com. The IP is 192.155.92.228

For some reason, I don't seem to be able to get the mail server to run. Whenever I send a test email from the outside to a virtual alias I set up, it bounces, stating "192.155.92.228]:25: Connection refused]. Testing the mail server using the tool at http://mxtoolbox.com also gives me "3/13/2013 3:26:13 AM Connection attempt #1 - Unable to connect after 15 seconds. [15.04 sec]"

Testing from within the box, however, indicates port 25 is working:

root@li589-228:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 li589-228.members.linode.com ESMTP Postfix (Ubuntu)

Any pointers as to what I'm doing wrong?

Would it be OK to offer the first one to help me solve this $25 via Paypal? If this offer violates some rule, please ignore it and I apologize.

Thank you.

Marc.

Your telnet'ing to your localhost address, not your ip.

I suspect if you look at whatever your using for your mail server, that in its config file it will only be binding to localhost.

That, or you have a firewall in the way

Hi Internat (greetings to Australia) -

thanks for your reply. I'm trying to use mail.ilovehamburg.com as mail server. Where is its config file and how do I change it so that the mail server will bind correctly?

Would it help if I shared the contents of the config file here?

Thanks again.

Marc

Howdy,

The config file for postfix is /etc/postfix.main.cf.
However if you can post the output of "postconf -n" and "iptables -nvL" that would be good
postconf -n prints non default postfix settings
and iptables -nvL prints the firewall table.

forgot to add you will need to restart postfix for it to take effect
/etc/init.d/postfix restart

Well, I'd love to send you the money... I made a promise after all when I posted this. Think of my karma

If you don't accept it I'll give the $25 to the Humane Society (I'm a dog lover; my Belgian Shepherd even has his own Web site: www.seemydog.com)

And thank you so much again.

As a parting note, your webmin installation is listening on the default port, 10000. Recommend you either change it and/or firewall it off.

Derfy, you're kind. I've changed it right away. Any suggestion as to in what range it should be?

I usually go 50000 and above.

Thanks, Derfy.

And Internat, $25 just went to the Humane Society, helping dogs (http://cpix.org/2013-03-13_06-34-35.png), as a token of my gratitude for your help today.

Thank you again!

thats awesome
