Ubuntu Servers :: How To See Which Mail Services I'm Using
Nov 29, 2010
I recently became responsible for a server running Ubuntu 10.04. I am trying to figure out how its outbound mail service is setup. Everything is working fine now, I just want to document how it is setup so if I need to rebuild the box I can do so without too much trouble when the pressure is on. It is a pretty basic setup, the only outbound mail gets sent from php scripts, the server does not receive incoming messages. Is there a place I can look to see what service is sending outgoing messages?

We have our web site hosted by Go daddy and they provide us with the mail service as well. But there are a lot of constraints with the mail service with regards to the number of mail boxes, size per box, relays per user and so on.To avoid this, we are looking at other options. One is to have our own mail server but it will require a lot of infrastructure and expertise. But Amazon web services looks nice. They have infrastructure needed and all. One thing on my mind is the reverse look up of the mail servers. They wont be associated with the domain as both would be on different hostings. I am open to both windows exchange server as well as Linux server. Has anyone done this before or has any idea about it? I have gone through some of the threads in their forum and there are a lot of mixed views about it.And main concern everyone views is the reverse lookup. This could lead to all the mails sent from my server tagged as spam at the recipient end.I could not make out in which forum to write and hence in newbie. If this is enough about networking or server please move it.

I got my hands on a couple old servers. An HP tc2021 and a Proliant ML110. Sure they're ancient, but I thought they would make a couple of great Ubuntu Servers for a new "start up" business I'm trying out. Now I've got to decide the best scenario to distribute the load between the two servers. I'm going to make an internal domain and will probably be running the following: Kerberos, Samba, Apache, Postfix, mysql, bind, dhcp, SVN, GCC, and Nagios. So in summary, I'll have the following roles; domain controller, web server, file server, and network monitoring services. how they would handle splitting these services up between two servers?

Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.
A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.
A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:
ISP supplied CISCO router
Draytek VigorPro 5510 UTM
Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:
CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server
I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...
I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?

I set up my mail server using the guide here: [URL] I am able to receive mail, I can send mail locally, but I can't send to external addresses. This is in my mail.log: Quote: Jun 30 14:40:43 Server postfix/smtp[10725]: 2FD9322015BF: to=<myemail@gmail.com>, relay=none, delay=1634, delays=1484/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.65.27]:25: Connection timed out)
This is my main.cf:

The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

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.

It would seem MySQL and VSFTP no longer create pid files and monit requires a pid file to work. Is there any way to force MySQLD and VSFTPD to use pid files or am I out of luck?

I have three HP diskless thin clients and a Server with Ubuntu installed. I'd like to be able to run the desktop version of Ubuntu on the clients straight from the server, akin to what would be possible on Windows Server running terminal services and thin clients. Is this possible?

I have a server running 64bit lucid and while trying to get a script to run on boot to start Davmail I appear to have broken something. I have webmin installed but I have been trying to do the majority of things via the command line. I now have davmail starting at boot but a lot of other services don't start anymore, including apache, mysql and webmin. Fortunately SSH still works and I can start apache and webmin from the command line without any problems.

How do you enable/disable the autostart of services. For example let's say I know I'm not gonna use apache and mysql for a while and don't want it to autostart anymore how do I disable it ?
And then once it is needed again how do you enable the autostart again ?

I downloaded the latest 10.4 server CD with the intention of running a small Ubuntu Enterprise Cloud. I am following the directions here: [URL] Ive got 2 laptops that are capable of the tasks assigned to them. Both have dual core Intel chips that are VT enabled, 4GB of RAM, 250GB hard drives. Ill use one ( "server" ) as the front end server running cc, clc, walrus and sc.The other one ( "node1" ) will be the only node controller on my little network. Ive also got another laptop as a client, running euca commands to make instances and what not.These three laptops are connected to a switch. server is 192.168.1.100, node1 is going to be 192.168.1.110, the client laptop is 192.168.1.120.
the server seems to install fine, I select Install Ubuntu Enterprise Cloud, use it as the Cluster, give the cluster a name and 10 IPs to assign, 192.168.1.150-192.168.1.160 After the server is done installing and reboots, I boot the node machine off the CD and again select Ubuntu Enterprise Cloud. It's at this point the install craps out, because it does not recognize a cloud computer on the network.
Indeed, as I go to the server I run
Code:
ps -aux | grep euca
and see nothing running. So I start the eucalyptus service, and run
Code:
sudo euca_conf --list-clusters
and nothing shows up. Ive done some googling, ran some more euca_conf commands, registering the cluster, enabling walrus, cloud and sc. I can access the web gui on the client laptop, then restart the node install on the node laptop. This time it does see the server as a cluster controller, but when it tries to fetch the preseed file, it seems to not know the cluster's IP, as the red box that complains about the lack of a preseed file lists the URL as [URL] ( or whatever the file is called, I dont have the error in front of me. )

I can view my website, and ssh in when I've logged in already at home, but if the system gets rebooted, and gets as far as the login screen, I am not able to view the web site or ssh in. I was wondering how to set things up so thatthese services are running independent of logging in.

I have Apache Server working online under Fedora Core 6. But before I installed and configured everything, I've been testing in Fedora 12. The problem surges here, when I start the httpd service, every supuse 404 action on a web browser, takes me to localhost. I mean, if I enter google.com, no error, just goes to localhost, http://asdasd, no error, gives back localhost. I used to ignore the problem 'cause I thought it was a problem on my apache, but when I installed the Server on the Fedora Core 6 machine, I found that I have the same problem there. Of course, it only occurs when I am browsing through the same machine that has httpd started. Does anyone know how to change that??

i have installed apache and bind on my server and i've also registered a dynamic domain through dyndns as jan27.dyndns.biz. i am able to successfully host my own webpages using this method.
then i registered a domain name (lets call it "blah.com") through namescheap.com and have registered my nameserver to my ip address. after reconfiguring the my external zones in bind and restarted my services, i am unable to reach my webpages through the new domain name.. www.blah.com and blah.com would lead me to a opendns.com page but interestingly ns1.blah.com loads my webpages successfully.

So I want to get mount/umount option under right click services menu. I went to Dolphin -> Settings -> Configure Dolphin -> Services -> Download New Services and from there I installed KDE CDEmu Emulator and MountISO. But neither of them is showing up in actual context menu. Neither in Dolphin -> Settings -> Configure Dolphin -> Services for that matter. I tried to install them as normal user and as a root. I went to have a peak in /usr/share/kde4/services/ServiceMenus/ but they aren't there as well... It's just me or lots of things seems to be not quite working in 11.3?

I have a good grasp on windows server 2003 but I don?t want to pay outrageous license fees for software and services and clients. I am newish to terminal as I only know a few commands. I have no problem installing services for the server edition for 10.04. Its just understanding whats going wrong to troubleshoot. I guess there is you guys and I have good working knowledge of Cisco's IOS's so I understand things like routing tables and interfaces and such for troubleshooting.
Questions I have... Can I install the desktop version of 10.04 and just install the server services? I was looking at the server guide [URL] and would like to know if these can all be installed on the desktop edition without too much trouble. I would imagine one could just use the server edition but I would really want a graphical user environment for some of the activities, if not all that I can. This would be becuase on my skills in the CLI. I priced out a server from Dell. I fits my budget perfectly if I go the Ubuntu 10.04 route. I was wondering if anyone sees any conflicts with the hardware for the Ubuntu OS....

so my server is doing fine, but there is one odd thing I would like to fix. When I start and stop services, the CPU is maxed out for about five seconds each time. The services start the same speed, but it still does this. Small things like lm_sensors don't do this, just things like httpd and sendmail. THis server was upgraded to Fedora 11 with a netinstall CD a few months ago.

I handle several hundreds of domains. Mails are handled with google apps (but previously I used to have a full postfix/courrier setup with virtualhosting). Now what I need is to be able to send mail (newsletter etc...) from my web servers, but I don't need to receive mail on these servers.

I have several forms created on my server. I'm running Ubuntu server 10.04.
I was running Ubuntu server 10.10 up until Tuesday Night. I decided to go to Ubuntu Server 10.04 in favor of the long term support of it.
While running Ubuntu server 10.10 all my forms worked and would send the form data to my email without issue.
Now after transfer the site to Ubuntu 10.04 I'm not getting any of the email messages. I have verified my email works by sending a test email directly to the account.
