Server :: Servers Not Routing Email Appropriately?
Sep 1, 2009
I have an environment of roughly 30 machines that all have ssmtp installed with identical config files. I also have logwatch installed on all of them, and it runs nightly as it is supposed to. The problem is that any given night, a random number of machines do not send out the resulting email from logwatch but instead dump it to ~/dead.letter. The number of failures changes every night, but most of the time it is between 20 and 30 of my servers.

I have recently setup a new mail server and have simulated sending and receiving on the new email server. The new email server will replace the primary one.I would like to setup the new email server in parallel with the existing one.This way i can observe issues that might occur and be aware of what could go wrong. I want to received mail to be delivered to both mail servers at the same time.I would like to use postfix, exim i find a bit to difficult to understand.I have thought of using transport maps, the only problem is that you can only forward mail to one server at a time using transport maps.I think recipient_bcc_maps and sender_bcc_maps could work, i would just like ideas of how i can do this.

I have a user setup to receive email, which I would like automatically to be sent into a program that I'm writing. Should I be looking into procmail, or is there a shorter way in /etc/mail (for sendmail) to route all of a specific user's email into a program? I don't care whether the emails are ever written into /var/mail. CentOS 5.3, kernel 2.6.18-128.1.6.el5, sendmail 8.13.8

I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.

I will be getting an old and decrepit laptop (the PS2 channel went out). I have decided that I would like to set it up to be an email and minor data server. The only problem exists that I have never setup a server, yet alone a linux server before.
I want the server to allow user authenticated access to a certain folder on the machine where other clients can go and copy and paste files for the data server portions and I want it to download emails from multiple domains (Gmail, a Microsoft Exchange Server, and from a private domain) and then allow other clients to log in and download those messages (I would like to keep each domain's emails separate so the client has to specify which domain's emails to download).

I am setting up a new email server by following the Flurdy guide. I can send but I can't receive. I can telnet in with both the IP address & telnet mail.domain.com 25 I'm not using or loading shorewall because I will be relying on the firewall that is in the router. I have been following the test section of the flurdy tutorial. I am tailing the mail.log file and only see the status as being different from the example
"status=bounced (mail for domain.com loops back to myself)"
It seems like it is getting through to the server but then getting rejected.

I recently bought my own domain name and have started working on my website. I am way excited about setting this site up. My question is, what would be the best way to setup an email system where users are able to login and check their email...I guess like, a web-based system? Then they can configure a client if they wish with their email address.

I recently setup a server running subversion. It is working well and all, but I am curious as to how to make it send out email alerts to my team when a commit occurs.Also, are their any good GUI tools to manage a subversion server in Ubuntu. The command line is fine since I made some scripts but a nice GUI would be great! Maybe that could be a fun project to work on.

I've got a hankering to upgrade my home PBX from Trixbox on CentOS to SipXecs on Ubuntu 10.04 LTS.
The current Trixbox setup is running on a Gigabyte G33M-S2 with 2.2 GHz Intel Core 2 duo (There ain't no kill, like overkill). My needs are... ahem... modest, to say the least. The user base is currently five (5) people (all family members)... and would never grow beyond 10.
So, the Intel Atom D525 looks like I could cut down on power consumption. I'm thinking of going with the Gigabyte version found here [url]
If it works out well, I'm thinking of moving my email server (currently on Qmail, and showing its age) to a D525 board, and switching to Postfix.
Has anyone had any thoughts, experiences (good or bad), and/or "gotchas" with the Atom boards as a server (no gui).

I have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?

I have been trying to solve this problem for two days now looking at various forums and websites but can't really figure out what's going on here.I have setup postfix on my ubuntu and I can send emails using "telnet localhost 25" and the ehlo thingy. Apache can also send emails. My problem is with incoming emails. When I try to send an email (through Gmail) I get the following error message:
Code:
Delivery to the following recipient has been delayed:
root@example.com

Have someone used Linux heartbeat to send email when the Slave server becomes the Master? I've read I can configure the MailTo under.
But I really don't know how to do it. I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node.

Does anyone know how to go about setting up a secure IMAP email server that is able to be accessed from outside the network? Similar to how you can access your google email account from your computer using Thunderbird.

I'd like to create a swap partition having already reached the four partitions per disk limit. So I'd like to create an extended partition and move some partitions into it. The question is which partitions to move and where to create the extended partition.
Some partitions have so much data that I cannot back them up, so I'd prefer to avoid performing operations that might risk them.
By the way, is there a command line tool that provides equivalent output as gparted?

What program should i be using to accomplish this? I've used nullmailer before but that assumes you have a fixed smarthost somewhere which I don't.

routing tables using "ip route 2" I have a server(server1 from now on) with eth0(internet connection) and eth1(lan connection). eth1 have 2 more alias devices = eth1:1 and eth1:2 On my server 1 the eth0=public ip, on eth1=192.168.10.1/24, eth1:1=192.168.20.1/24 and eth1:2=192.168.30.1/24 server1 is running squid and iptables to all 3 networks (eth1, eth1:1 and eth1:2) All of the clients have access to internet. Now what i want to do is add 3 more networks via a router(linuxBox = server2 from now on) connected to server1 in eth1. so the network will be like this:
Code:
server1
eth0=internet
eth1=192.168.10.1/24 (connected to server2 and other clients)

So my server running FC4 died last night and I decided to go ahead with the long-awaited upgrade to FC10 while I was rebuilding my server. I use my server for a number of things including, but not limited to: router, firewall, web server, mail server... I have a typical configuration process that I have followed since before fedora, and it has worked well for me up through FC4, but my usual config process doesn't work on FC10.
First of all, I don't want SELinux running, I didn't see an option to not install it during the FC10 setup, so how to I properly disable or uninstall it afterwards? Second, I was unable to even configure the server to route traffic from my internal network to the web, here's the process I usually go through for this:
[Code]...
I don't have a static IP from my ISP, so I'm not quite sure how to add the default route. I think I need to do something like "route add default gw xxx.xxx.xxx.xxx eth1" where eth1 is my external NIC, correct?
What else do I need to do to route traffic? I noticed that I wasn't even able to ping my server from the internal network even though they are on the same subnet, my server's internal NIC has an address of 192.168.7.1 and my computer on the network has an address of 192.168.7.2. If I can get this going to I have internet access again at the very least, I can move forward with the web server, email, etc.

I have an Ubuntu 9.10 server installation which have been working flawlessly for some months. The server runs bridged networking, because of some VMs that runs on it. But, a couple of weeks ago the network connectivity have started to disappear now and then (usually once a day or so). Running "sudo /etc/init.d/networking restart" always kicks it back to life.
After a bit of debugging I noticed that when OK the routing table looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default 192.168.1.1 0.0.0.0 UG 100 0 0 br0
While when in the non-working state it looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default 192.168.1.1 0.0.0.0 UG 100 0 0 eth0
default 192.168.1.1 0.0.0.0 UG 100 0 0 br0
Deleting the two routes to eth0 restores the networking again. Why these "erronous" routes gets added, and what adds them? How to further debug this?

I have one external ip address and a few domains. Would it be possible to have each domain on a internal domain and the box that sits on that external ip route to the internal. This would be for a number of server (mail, apache, imap, pop3, https ) So for example:
Some visit domain1.com ->external ip -> 192.168.10.100 Someone else visit domain2.com ->external ip -> 192.168.10.101 and so one with a number of domains
