We are having a webserver (mydomain.com) with apache and postfix. The mails originating from this server sometimes reaches to the spam folder of recipients. To avoid this, we have purchased a relay server. I configured it in the postfix. Now the mails originating from the websever is sent out via relay server. we can send 30K mails via the relay server per month. While analyzing this, half of the emails sent are to [email protected]
So I am thinking of routing the emails sent to mydomain.com to my mail server and rest of the emails are sent out via relay server. I know that we can do this via /etc/postfix/transport file.
my main.cf is having this entry for general routing
relayhost = [smtp.relayserver.com]:587
It does not having entry for transport file.
Can you please help me to include the transport file to main.cf and configure it to forward email to mydomain to my mail server. Even a good link is enough for me configure. THanks in advance.

I have set-up mail server on 192.168.6.1 (Redhat 6.1 Santiago). This server is in Russia. The server has no internet connectivity, so I have configured Mail Relay Agent on it as mail.x.com (In India) under /etc/postfix/main.cfg. I have made an entry for mail.x.com under /etc/hosts with ip to name binding. I am able to ping mail.x.com and also able to telnet to it on port 25 (SMTP) from this Russia server.
I then restart the postfix service and it comes up without any error message. When I send mail using mailx or sendmail, and then check the logs under /var/log/maillog, I get the below error message :-
>, relay=none, delay=1004, delays=999/0.02/5.1/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=mail.x.com type=MX: Host not found, try again)
The resolv.conf entry has a global dns server configured under it. But to my understanding, when I am able to telnet and ping this mail.x.com server, then why is th

Or if needed it is fairly easy to get back to the 'classic' gnome desktop as opposed to Unity.
You can just run this in a terminal:
sudo apt-get install gnome-session-fallback
Reboot and then select "Gnome Classic" on the login screen.
For a detailed walkthrough, check the page here.
Also note: In order to make changes to the panel settings, you have to use alt+right click, instead of just a regular right click.

Kubuntu 11.10 KDE Sudo error on every start up. Here is the fix for it.
location: linux.com - date: October 15, 2011
So Kubuntu 11.10 on my laptop (Ubuntu using KDE instead of Unity or Gnome) runs smooth but I was getting an error on every start up that said this:
Information - KdeSudo
No command arguments supplied!
Usage: kdesudo [-u <runas>] <command>
KdeSudo will now exit...
So I immediately went to google and found this fix, which after rebooting has solved this problem. It's pretty simple.
KDE Start > Applications > Settings > System Settings > Start up and Shutdown
Once here, choose "Session Management" and you will see a section that says "On Login" with three options:
Restore Previous Session (Default)
Restore Manually Saved Session
Start with an Empty Session ( Choose this one ) Then press "Apply"
All this means, is instead of restoring everything you were doing prior to shutting down your computer, it will start fresh with a new session. This is what I expect anyway since I always save my work etc... So I assume to man

MultiBooting fix with Opensuse
location: linuxquestions.com - date: June 8, 2013
A couple of months ago, I had seen the following, but first, as a pre-explanation, all the Operating Systems listed in my signature are all in one machine, mult-booting. What I had seen is this-- when I select Opensuse from Grub, It gives me an error about not finding /dev/root, and trying to manually resume from /dev/sda2, and whether or not It should try the dev-disk-id method or something like that. And, when I select slackware, it boots into opensuse, but freezes after the first few seconds. So I posted on this forum, no luck. Then I tried this--as root, in a different install, in this case ubuntu, open nemo as root, go into the dev directory, and switch the drive letters of opensuse and slackware. Poof! Slackware worked after updating grub, nut opensuse did not, and knew I had to switch the drive letters of opensuse and something else, but did not know what, and was forced to format and reinstall the opensuse hard drive (to be clear, each install is in a different 100 GB virtual d
