You do not have DNS set correctly. Make sure you are onto internet and all your network settings are fine.

Xanios · 08-04-2010, 12:44 AM

I'm onto internet.

I'm lost.):

linuxlover.chaitanya · 08-04-2010, 12:46 AM

Can you nslookup or ping any other domain from your Ubuntu machine? I doubt your network settings.

Xanios · 08-04-2010, 12:50 AM

I tried to ping another windows server machine, it works.

Code:

xanios@ubuntu:~$ ping 192.168.142.149

i tried to nslookup the same windows server:

Code:

xanios@ubuntu:~$ nslookup 192.168.142.149
;; connection timed out; no servers could be reached

linuxlover.chaitanya · 08-04-2010, 12:54 AM

That is the issue of your DNS server. You are not able to resolve the domains. What does pinging to google.com say?

Xanios · 08-04-2010, 12:58 AM

Is it this:

Code:

xanios@ubuntu:~$ ping google.com
ping: unknown host google.com

EricTRA · 08-04-2010, 01:00 AM

Hello,

@linuxlover.chaitanya: can you elaborate why relayhost needs to be set to the smtp.gmail.com:587 value? My Postfix is sending out (and has been doing so for over a year without problems) and that parameter is empty in my configuration.

@Xanios: What have you changed (trace back your steps) so that you go from: 1. connecting to GMail but being refused connection
to
2. not being able to even pinging google.com?

Kind regards,

Eric

Xanios · 08-04-2010, 01:03 AM

Hi Eric,

I only changed to relayhost=smtp.gmail.com:587 in main.cf, but after that i changed back i still got the error posted on yesterday.

Hello,

I'm not at all a Postfix guru but in my opinion the relayhost parameter doesn't need to be set since you refer to it in the mydestination parameter. On the other hand it might be necessary if you need to authenticate.

But if you set it, you need to set the domain name in brackets like this:

Code:

relayhost=[smtp.gmail.com]:587

Can you change that, restart/reload postfix and try again?

Kind regards,

Eric

Xanios · 08-04-2010, 01:18 AM

Hello,

i changed that, restarted postfix and still get the same result:

Hi again,

Sorry. I forgot i have a backup of yesterday's work, so i shall use that.

this is the output i've got from the backup:

it's always good to have a backup

So how shall we continue from here?

thanks

edit:

it's totally crazy lol.
for this file i didn't change anything at all...
i just sent a mail just now and viewed the log mail again and i got:

Code:

Aug  3 23:39:31 ubuntu postfix/error[2566]: 95C2A40BFA: to=<xanios@server.com>, relay=none, delay=0.01, delays=0/0/0/0, dsn=4.3.5, status=deferred (delivery temporarily suspended: unable to look up host smtp.gmail.com: No address associated with hostname)

Since he is using an external SMTP server to send mails, and also need to authenticate to that SMTP that is owned by google, he needs to tell postfix which SMTP he needs to use to relay mails and authenticate to. Setting up a relayhost will allow OP to send emails from his internal mail server to any server on the internet. I have a zimbra installation with similar purpose for sending and receiving mails from outside using my Go daddy hosted SMTP server with authentication and it works fine. Free relay servers can also be used in this sense but using a trusted relay will not mark his messages as spam.

@OP,

You need to look into the network settings you have. You do not have correct DNS settings and that is why you are not able to resolve domains. Try to use global dns 4.2.2.2 and see if that solves your problem. But a better solution is to ask your ISP to provide DNS server settings for you.

Xanios · 08-04-2010, 01:51 AM

Hi,

How to use global dns server 4.2.2.2 ?

By the way, i guess you know i'm using nagios to send email notifications to gmail when the services go down, right?

linuxlover.chaitanya · 08-04-2010, 02:05 AM

Yes. Nagios and postfix should both probably use the system network settings as far as I can guess. What are the contents of /etc/resolv.conf file?

Xanios · 08-04-2010, 02:08 AM

Hi,

i typed

Code:

sudo vi /etc/resolv.conf

and this is the output i got:

Code:

# Generated by NetworkManager
domain localdomain
search localdomain
