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.

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).

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. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.

We run a service in which a customer types in a form and gets a confirmation email after submitting the form. We are on a server with no control panel. We are running CentOS 5.
When we did our testing sendmail sent mails just fine and I was able to receive them. After we went live we found that 75% of our emails are being rejected by other mail servers. Doing research is seems that the headers indicate the emails are coming from 127.0.0.1.
We need to correct this problem, as well as do everything we can to reduce the risk of our mails being marked as spam. We do not receive mail on this server, but rather send mail. We have another email server on another server for receiving mail for our domain, which is already configured with cPanel (which doesn't have a problem).
We can not use cPanel on this server because of certain security restrictions.
I know that sendmail is cryptic to configure. We are willing to switch to Exim if necessary.
As far as installing Exim, I understand it's as easy as:
yum install exim
yum remove sendmail
system-switch-mail (if installed)
But as far as setting up Exim for our needs.

I'm going to start a new thread because previous searches have not totally satisfied my question. I've read all day about doing this but each inquiry leads to discussion of configuring the router. I am also not network savy. I would like to set up an FTP server on my home computer (presently Ubuntu 8.10). I have only one computer. I am using DSL with my telephone line for internet connection. I do not use a router.
Is it possible to do this with no router and only a DSL ISP connection?

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.

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.
