CentOS 5 Server :: Postfix And Hosts File - The Mail Server Could Not Deliver Mail

Mar 20, 2011

I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:

<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk.

Server :: Is Server Pointing To Wrong Root Document?

Mar 7, 2010

I'm not exactly new to the linux world. I've been messing with it for six months now. I recently decided to host a public web server out of my home. The is nothing business related merely personal.Now that you have a brief background I will bring you the technical details.I'm apache2 with php, joomla, and mySQL on openSUSE 11.2. a dns server is currently configured. My problem is as follows I set up apache initially and used the default index.html page which simply says It Works. I configured my DNS at the domain registar godaddy.com. After changing the A record to point to my IP the server worked. I then proceeded to install Joomla which installed correctly.Now here is my problem. When I attempt to pull up my domain it appears my DNS is longer working properly and get a DNS error. When I attempt to go directly to IP with my server I still get the initial index.html that says it works. I'm not sure how this is possible and I have cleared all dns info, temp files cookies ect.... I have also had other people test this is as well. I've check my root document pointers for the apache website and they all point to the correct location.

My set up is as follows

Modem
Router
Windows 7 Machine
Sun Microsystems Virtual Box with openSUSE with the network adapter bridged so it can obtain an IP from my router

I'm completely lost at this point and have spent 2 days trying to resolve the issue, any help would be much appreciated. I look forward to everyones reply.

CentOS 5 Server :: Configure A Mail Server Over A Home Internet Connection?

Feb 12, 2009

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.

Server :: How To Get Any Mail Generated From Apache Site On Centos Server

Jul 22, 2011

I am running a CentOS 5.6 Server with a website and Forum. The website has a contact form and users can email various people in the organization. I have setup sendmail to send any mails like this to my email address on a Windows machine.The problem is that there emails don't have a header which has the senders original email header. It comes from localhost on my sendmail. How can I get any mail generated from the apache site to ALSO send mail to root on the Centos Server? That way I should be able to see the header and report the spammer or block them.

5 Server :: Mail Sent From CentOS Server Received With (No Sender) / Sort It?

May 23, 2011

I am using Postfix on CentOS to send mail through a relayhost. The mail sends fine, but on certain clients such as the mail client on the iPhone or Windows Live Mail, the message is received with '(No Sender)' in the sender field. The Apple Mail client on the iMac works just fine.

Here is the PHP code I am using to send the mail code...

Wondering if there is a configuration setting in /etc/postfix/main.cf I can use to fix this problem. I have scoured the help files but have come up empty.

Server :: Centos Virtual Server Mail Setup ?

Nov 3, 2010

I just recently purchased a vs from a company and i am trying to set up a web site on it with kloxo and set up the mail for it upon setting up the mail settings it says:

"It is very essential that you set the my name to a properly resolvable hostname, since otherwise, many public mailservers like hotmail will reject mails from your server"

Now this is my first time setting up a vs before i have set up linux vm's to get email access but that was about a year ago.

CentOS 5 Server :: Mail Server Keeps On Hanging / Stop It?

Feb 1, 2010

Our mail server keeps on hanging after a while. This happened after there was a breakdown in electricity supply and the server room air conditioners stopped working for almost half a day. We are not sure whether this is a server hardware problem or a coincidence with a break-in attempt or malware activity.

Following are the message from the server log code...

Server :: Build The Virtual Machines To Exclude The Actual Mail Files And Mail Logs From CentOS?

Oct 12, 2010

I have to administer a few mail servers, a mail log server, 4 nameservers and a web server -all running on Centos 5 server distributions. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and mail log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves. I have already installed VMWare Server 2.0 I have a few questions:

- How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program?
- How do I actually do this cloning? Is there a tutorial on how to do this?

Server :: Mail Server Migration - How To Deliver Locally AND Forward Mail To New Server

Jan 21, 2011

Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.

I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

Ubuntu Networking :: About Several Domains Pointing At One Server?

Feb 27, 2011

I'll post an scenario and hopefully you can help me understand the concept and put me in the right track and do what I intend, if possible. Let's say I have a dedicated server with 2 static IPs each with an associated domain, let's call them www.site1.com and www.site2.com. Now, apache is running on it, I'd like to redirect anyone coming from site1.com to /home/site1/public_html and anyone coming from site2.com to /home/site2/public_html.In short, apache serving 2 entire roots depending on the accessed IP/domain. Whether the sites root are in the same parent folder, such as /home/site/site1_public_html and /home/site/site2_public_html or like above doesn't really matter, as long as it works.Additionally, do something similar with Postfix, so that I can have it running imap/smtp for foobar@site1.com and foobar@site2.com on the same server.At this moment, both apache and postfix are working, and we host only www.site1.com with the respective foobar@site1.com. But I'm not sure how to proceed or even if it's possible to achieve the above solution.

Debian Configuration :: Install A Multi-core System And Configure It To Run Several VMs, One Each For A Firewall, A Caching Proxy Server, A Mail Server, A Web Server?

Jan 25, 2011

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.

In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

Server :: E-mail Server Similer To Merak Mail Server ?

Aug 20, 2010

I was using an email server from Icewarp, Merak Mail server V8.0.3 with a keygen for total full free use... I liked this server package... as everything is in there I need and it is controllable from a single window. Now I am planning to move to Linux... They have a Linux version, but not stable and expensive. Is there any thing almost free/less expensive (Specially they need yearly payment for upgrade of even the anti virus and anti spam)?

I need a almost same thing (except of the ftp and VoIP) like Merak (because that I really liked for ease of administration) in Linux? Like a Qmail with real strong Anti Virus and Anti Spam, with unlimited domain and user+autoresponder, mailing list, etc all but controllable from one single GUI?

Ubuntu Servers :: Pointing / Hosting Domain Name To Server At Home?

Oct 13, 2010

I'm using Ubuntu Server (32bit) on a machine at home. I've bought a domain name(s) via Heartinternet.co.uk and my ISP is Bethere.co.uk I have installed my LAMP Server on my home based server and it's accessible via my static IP address. HTTP is forwarded on my router to my Ubuntu (web)Server. Now then, in laymen's terms, I want my domain name to resolve to my Ubuntu Server. I have installed and configured Bind9 to this guide found online: http://goo.gl/M3Pk i understand that I need to do this in order to 'host' the domain name. Or alternatively, if my presumptions are correct, I could leave the domain name with the registrar and use their DNS config panel to add an A record to point at my webserver (static IP address)???

If I forward port 53 (default for DNS) to my server (after setting up bind9 correctly) and within my domain name hosting options change the nameserver settings to point at my static ip address then would this be enough to host my domain from my home network?

I feel I nearly have a whole picture but...not quite. There's a multitude of vague guides on the internet (vague or I'm not reading them properly!)

Server :: Sendmail Bad Mail Location CentOS 5.5

Nov 18, 2010

We have moved from a Windows based SMTP server to Sendmail on Cent 5.5. We have a special application that was written to look at the "BadMail" folder on the Windows box. I am told by my developers that it is capable of monitor remote locations and they just need to know the format or extension of the badmail files.

My question is what is the default location of the badmail folder in Sendmail? This is a default install from CentOS.
