CentOS 5 Server :: Can't Receive Emails - When Primary DNS Went Down ?
May 11, 2011
I'm wondering why we can't received email when our primary DNS went down. We have slave DNS but don't know why we can't receive emails. Internet is working properly. The mail file in /etc/configuration on slave dns are there & the zone file is added. I edited the mail zone file to see if it works & restarted the named service. But still we can't received emails using the slave DNS. Do I need to reboot the server?

I have configured Postfix on a Ubuntu 8.04 box using this tutorial:I can send emails but I cannot receive any email because of a "bad recipient address syntax:"The log from /var/log/mail.info says this:

It is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.
PS. I was thrown into the position and have limited knowledge. I am used to a GUI.

I've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL]
2) All other users can receive and send mail from/to any domain.

Our main DNS resolves to a windows 2008 server box. What I want to do is have a secondary box with Ubuntu to receive sent emails (our@our.com). The problem my brain cannot get around is the DNS resolves to the windows server 2008 box(which host the website as well), how can we allow the email (ours@ours.com) to go to the Ubuntu email server even though the DNS name resolves to the windows server? We need the Windows Server but just Don't want it hosting our mail.

My email server (Postfix + Courier + virtual dropboxes) can receive internal emails, but if the email is sent from the exterior (like Gmail or Hotmail) this email is returned to the 3?rovider (like Gmail):Delivery to the following recipient failed permanently:xxxx@xxxxxxx.xxxTechnical details of permanent failure:Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, no mailbox here by that name (#5.1.1) (state 14).
----- Original message -----MIME-Version: 1.0I've tried a lot of things, I've used this guide:http://flurdy.com/docs/postfix/My Ubuntu Server is 10.4 (Lucid), I had the same configuration with a previous Ubuntu version and everything was right.

I want to setup an email client in order to send/receive emails, but since i am experiencing some issues with my ISP, i decided to setup an SMTP server with Postfix on my machine.The problem is that i can receive emails but i can not send.I read almost every thread in here refering to Postfix, but i could not find the problem on my configuration.So here it is..
Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first

I am working for the first time on a dedicated server with CentOS. I have sendmail and postifx installed and I realized all the emails send by the server are redirected to my own private address.
For example if I want to send an email to "luc@test.com", I will receive it in my box (ex "paulin@gmail.com")... I also receive in my box the logwatch which should be send to root@serverblabla.live-servers.net
That is very strange and I really don't understand what does that.

I recently purchased a domain and I have setup what I believe are correct dns records from the domain companies control panel. I have the domain pointing to my server and that's working fine. I also have an MX record for my domain. Now, I can send emails from my email account just fine however I cannot receive any emails coming in to my account. Heres an example:
[dalton@int-interactive mail]$ echo "hello world" | sendmail -v dalton@int-interactive.com
dalton@int-interactive.com... Connecting to [127.0.0.1] via relay...
220 int-interactive.com ESMTP Sendmail 8.13.8/8.13.8; Sun, 21 Aug 2011 14:45:16 -0400

I'm having a little trouble with ClamAV. Everytime someone sends me an email I get this error in my Webmin Mail Log. Now the mail works and it goes to the quarantine or to the user mail box but this error fills up my mail log and I'm assuming it is not using ClamAV virus definitions to scan the mail? How would I get rid of this error?
I checked in my /etc/clamd.conf and I have AllowSupplementaryGroups yes. What can be causing this error?
I am using ClamAV 0.96.1

I have it config'd to send and receive on multiple accounts and they all receive email, but SMTP times out and even sends no matter what account I try to send with. I thought maybe security and dropped the firewall and still won't send. No matter which account I try to send to it says its timing out trying access I have no problems on my Mac so no network problems. For grins I install Thunderbird and setup one account and same thing received but no send. What could it be blocking outgoing email??? I have CentOS 5 with all available updates.

I have setup Ubuntu servers as LAMP machines but that's pretty much it.
I need to work on an existing CentOS server that I will see for the first time tomorrow. I am told that, as of right now, it is "just serving the internet." The goal is to set it up to be a primary domain controller by which I mean:
1) A user should be able to login to the server from any of the workstations and then see their server stored documents
2) The clients will be a mixed bag of Linux, Windows and Mac machines
I could use a push in the right direction as to what I need to do to get this all setup. I know how to setup users and home folders (I use webmin typically and I understand that there is a version for CentOS) but clearly there is more that I need to do. I am really curious as to how I would map the necessary drives on the client machines upon login and have the users have automatic access to their data regardless of the client machine they log in to.

I want to set up an installation server for CentOS 5.5, using PXE for boot, kickstart for package selection (one for server), and NFS for share all files needed.I've succesfully completed a fresh installation of CentOS5 from the DVD for one of my servers (virgil), and I've copied the anaconda-ks.cfg generated by the installer to my install server (beatrix).
Next, I've properly configured the /etc/dhcpd.conf , the /tftpboot/pxelinux.cfg/<IP_CODED> and the /etc/exports for NFS sharing on beatrix.Then, I've copied all the first DVD of CentOS5 content in this folder on beatrix: /opt/CentOS_install I've tried to start virgil from ethernet, and all has gone ok, with the kickstart and so on! But I've decided to apply the updates (new kernel, sudo, xorg, ...), so I've deleted the old rpms from /opt/CentOS_install/CentOS and copied the new ones (downloaded from http://mirror.centos.org/centos-5/5/updates/x86_64/RPMS/). So, I've launched the following commands to recreate the repodata:
root@beatrix:/opt/CentOS_install/ # mv repodata/comps.xml CentOS/
root@beatrix:/opt/CentOS_install/ # rm -fr repodata
root@beatrix:/opt/CentOS_install/ # createrepo -p -o /opt/CentOS_install/ -g comps.xml /opt/CentOS_install/CentOS
But when I try to reinstall virgil, an error message appears, telling me that a package (perl-DBI-...) isn't present in the media.After some debugging, I've noticed that in the /opt/CentOS_install/repodata/primary.xml.gz there isn't the correct path for the rpms. If you look at the original primary.xml, the "path" is like:path="CentOS/abcxyz.rpm" while in the generated file (with createrepo) the path is:
path="abcxyz.rpm".How can I recreate the repodata with the correct path information?

For starters, I apologize if this turns out to be a double post. My windows laptop hiccupped in the middle...
So I had a Linux box with two drives running happily for years. Both drives were in the same logical volume, and the second had a file system on it.
The the boot drive croaked. I replaced it and reinstalled CENTOS (making sure, of course, to be careful to use the new drive). The I put the second drive back into the volume group (and that's it).
I'm assuming I probably need to create a new logical volume, because that's how it was before, but I really really don't want to format it.
Am I missing a step or am I screwed?
Fsck -l showed the following output both before and after I put the drive in the volume group. code...

I have a CentOS 5.3 system running a recently installed Postfix (I removed sendmail so I positively know it's running Postfix).
I am able to send out email as user root, but when I change to another user on the same server, the mail delivery fails.
Here's what's captured in the /var/log/maillog:
Here's my main.cf
No changes to other Postfix files since install, so they are the default files.

Howdy. I'm trying to get mailman up and running. I have CentOS 5 (hiab) and qmail. I did yum install mailman and that went fine, I set up apache and can see the mailman pages via htttp.The issue now is with sending mail, whenever I send emails to the list I get: 511 511 sorry, no mailbox here by that name
So I'm assuming my alias files/.qmail fies are in the wrong spot. The contents of my .qmail are (respective to the -admin, -bounces, -etc)

I have two situations here :
1) I have my Nagios running on the linux box and BMC Remedy Server on the Solaris box. I have simulated a mail from Nagios to be delivered to the Remedy server. But the Remedy Server does not receive it. I even tried snooping on port 25 but nothing has reached the box.
2) I have my Nagios running on the linux box and BMC Remedy Server on the Solaris box. I have simulated a mail from Nagios to be delivered to the Remedy server. I snooped on port 25 on the Solaris box. I could see the mail reaching the box, but it is not being forwarded to the Remedy inbox.
