Server :: Configure Mail Server For Outgoing Only ?

Jan 14, 2010

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.

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 :: Setting Up Postfix For Outgoing Mail?

Jul 27, 2011

I'm setting up a server and trying to make it *very* secure. Before I configured my web stack, I was about to install some security packages, Tiger and Samhain, but these packages wanted to install sendmail so that they can send outgoing notifications. From the reading I've been doing, I believe I want postfix instead of sendmail. It is my (perhaps mistaken) belief that installing postfix first will prevent them from installing this sendmail I do not want.

I want to install postfix with the following goals in mind:

* let PHP scripts send mail using the mail function.

* various system notification functions (cron, etc.) will be able to send their emails

* emails destined for root@localhost will be redirected to admin@mydomain.com

* let tiger and/or samhain send their notification emails

* NO INCOMING OR LOCAL MAIL IS PERMITTED. Because mail for my domain is handled by google apps, nobody will be checking mail on this server. Also, this server has very limited disk space. It is therefore very important that we don't have mail accumulating in boxes that will never be checked.

* no unnecessary ports, services, or cron jobs are running.

I've been reading a variety of pages that describe postfix setup on Ubuntu but these articles are imprecise, incomplete, and describe installation of things I don't want like POP/IMAP/etc.

There's also one final wrinkle. I will be setting up postfix to send via Amazon SES.

OpenSUSE Network :: Mail Server Outgoing Address?

Feb 15, 2010

I just set up a new router for our home office. I've enabled traffic logging, and I'd like to have the logs emailed to me. However, in order to configure email-notification, the router needs and outgoing mail server. Forgive me, but I don't really understand the terminology being used here. I've googled this a bit, but I'm not sure I now what "outgoing" vs "incoming" mean in the context. I tried using my gmail account as the outgoing mail server (smpt.gmail.com) but it requires TTLS encryption, and there's no option for that on my router.

So I figured I'd setup a simple mail server on my local network. I have a dedicated server machine, so I'd just configure a mail server there. But I got stumped at the first input box (in the yast module):"Outgoing Mail Server".That's what I wanted to use this server for. What is this "outgoing mail server"? I understand it in a normal emai context (I think) but this is confusing me. I've read through the HowTo on the openSUSE wiki, but it still doesn't answer this question.Isn't there some way to have a simple, local mail server (without MX records and the like) so I can send email from a local machine?

Server :: Postfix Filter Outgoing Mail By Sender Domain ?

Jun 17, 2010

Im trying to get postfix to filter my outgoing mail and basically drop everything that is not in my hash table.

So far I managed to get this going

Code:

Code:

Unfortunately those rules also apply to incoming messages. My goal is to disallow users on my host to change their "MAIL FROM" to anything they like and restrict them to domains I specify. I'm aware that the local part still is variable and a user of domain "foo.com" could use a email of domain "bar.com", but still some of my troubles would be solved if I get this running.

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.

General :: Configure Bugzilla To Use External Mail Server

Feb 13, 2010

Planning to put a bugzilla server for bug reporting at our office. I have loaded and configured bugzilla on one of our machines running CentOS5.4. And there is another machine on CentOS5.4 that is running Zimbra community edition. Both are distinct machines. Zimbra is running fine and so is Bugzilla. I want bugzilla to use this Zimbra server to send mails so that I can use this internal mail server for my purpose.
This is the first time I am putting up bugzilla and have never worked on it but documentation helped. But I could not find any reference on how to do this?
