Ubuntu Servers :: Setting Up Dns In Mail.domain.com?
Feb 5, 2011
I have created a mail server using citadel that seems to be working nicely. My only problem is the only way to access the server is to go to 71.114.220.3:2000 (it's running on port 2000). I would like to be able to access the server by going to mail.annarrankings.comI'm using godaddy for my dns and set an A record as host=mail, points to =@Then set the mx server to priority=10, host=mail.annarrankings.com, points to = @
I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.
Im an IT manager for a small company with a small ammount of users. We already use linux for our data server and I would like to implement a domain controller. All of our user machines are WIndows XP pro.
Ive been reading up on using OpenLDAP as an alternative to active directory.
What I want is just a simple active directory like server, with a GUI if possible.
What do I need to look at and how would I go about setting this up? Im fairly proficient with Ubuntu already, I just need to be pointed in the right direction.
Is it even possible to have my windows users be able to log in to their machines using an ubuntu domain controller?
To setting up the mail server for my site. The situation is such that it is necessary to allow access through the site (built under LAMP) to the mail server. Ligament postfix + dovecot good option? or who have a similar configs mail server.
I have a small home network running mail agents Evolution and Thunderbird, and connected to the internet via Comcast. Originally I used my campus office computer as a mail server, but encountered problmes because Comcast started blocking port 25, allegedly because of span problems. I need to change the setup on my campus office computer so it uses port 587 when functioning as an outgoing mail server.
Can anyone recommend a tutorial which tells me everything to do in order to accomplish that?
At present I'm, using Comcast's outgoing mail server, but I started having problems with sporadic blokage of outgoing mail with attachments, which Comast can't explain.
How to set crontab not send mail notification to the owner script if the script success running? because I'm monitoring mail server, and notification from cron is not necessary for me. I'm using ubuntu 10.04 server
i have registered two domain names that i want to use to connect to my ubuntu server. I was wondering how to do this i was looking at bind9 but that didn't work that great. The server is behind a router with firewall i can connect to it using the external IP address but i like to use the two domain names if that is possible.
I have two servers relavant here: mail.domain.com (1.1.1.1) - which is the nameserver and the mail server for domain.com. www.domain.com (2.2.2.2) - which is the www subdomain for domain.com domain.com (cname www.domain.com) - an alias for www.
The zone file for domain.com lists mail.domain.com as the MX server for domain.com. 2.2.2.2 is actually being served web pages as a virtual host. It's real hostname is www.anotherdomain.com. Mail for domain.com works pretty well, in general. However, if I attempt to send mail from www.domain.com (or its alias domain.com), I get "mail for domain.com loops back to myself" in the postfix logs. On 2.2.2.2 /etc/postfix/mail.cf has mydestination = www.anotherdomain.com, localhost. How do I tell postfix on 2.2.2.2 that mail for domain.com needs to be delivered to mail.domain.com?
The company I work for, as usual, is Microsoft-centric. I'm attempting to integrate my Ubuntu server into the domain to allow domain users to authenticate to the server and access file shares using Samba. Here's my current configuration:
There is an requirement, intranet people they may not have internet access but they want to send mail to external domain(internet),but in that intranet network one machine can have internet access. Is there any solution for this requirement.
I have wiped Windows and am running 10.04 exclusively. 32 bit, when setting up evolution e mail account i dont see where to enter password....where is it? anyone have link with screenshots? i know i can use regular hotmail but want to know how to use default ubuntu programs.
I still can't find a spot for password. options are, login, set preferences and a remember password checkbox but nowhere to enter a password
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.
Ubuntu Server 9.10I want to set up my dhcp server to also be my DNS server so do I skip these lines or point them at the same server that the config file is on?
In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?
I recently decided I wanted a web server so I installed Ubuntu and apache2 on it and it works fine. I installed forums on the site as well and it's working fine to. Problem I don't know exactly what to do with the site so I haven't purchased a domain yet (so to access the site you just type in the ip address).
I know this sounds really weird but I want to know if I can make a mail server without a domain name. I kinda want to use it for e-mail verification for the forum. I have been following this tutorial: [URL] and it seems i need a domain name. Is it possible? Also I am not using Ubuntu server, would setting up a mail server be much easier on there (or rather, does it come with a mail server?)
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:
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)
I have a Slackware 12.1 box with mail server running on Postfix and Dovecot. My domain name is,say, [URL].. I have another domain, mail.xyz.net. I want to use both the domain for incoming. Like, someone sends mail to [URL]... otherone sends mail to user@xyz.net. Both the mail should be received.
i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.
For example, if i send one mail from user1@mydomain.com to user2@mydomain.com the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to user1@mydomain.com or user2@mydomain.com (for example), so please tell me what do i do to get the mail.
I have a server running ubuntu 8.04 with apache2. What I'd like to know is how to go about setting up a domain name? I've looked at a heap of hosting sites, but they son't seem to allow you to specify your own IP address that you already have. Also, I'm not sure about what, if any kind of DNS software I would then have to run on my server. At this stage I'm only doing preliminary research about it I guess.
i have a question, it ought to be a simple task for most but im as noob as they get. In ubuntu 11.04 desktop, how do i change the hostname as well as setting the new domain name?. Temporarily its easy with hostname and domainname in terminal, but i want it to become persistant. Lets say i want the machine name to become computer01 and domain to become homenet.lan. Then i would change the /etc/hostname to contain computer01 only. But what i cant figure is how the new /etc/hosts is supposed to look, the old one is:
127.0.0.1 localhost 127.0.1.1 current_computer_name # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
But how is the new /etc/hosts supposed to look if hostname is to be computer01 and domainname homenet.lan?,
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:
I m using sendmail-8.13.8-2.el5 along with MailScanner-4.79.11-1
i want to set a rule so that user1@mydomain.com can send only to anotherdomain.com domain. sending mail to any other domain will be rejected. can it be done by sendmail or MailScanner ??
I'm trying to set up an mail filter for our domain. At the moment we're using ClearOS as the filter, works OK but I still get something through and the blacklist and whitelist doesn't seem to work. I was hoping to set up a mail filter on my own, using Spamassassin and/or something else. It seems I have to buy subscription at ClearOS to make it update better or something. I might just do that, it's just tempting to find a way to do it on "my own". I tried to follow these instructions but I don't seem to go anywhere... ...I began with setting up the base server as it is shown there. I've setup quite a few Linux servers, mainly as firewall/gateway kind of things but also some DNS servers, web servers and so on.
I have one mail server and the mail filter is supposed to be on the outside to filter mail before it hits the mail server.
I have a CentOS 5.2 server with hostname support.companyname.local It's used to run Request Tracker 3.8.1. I need to be able to send email from this machine and make it look like the email came from user@companyname.com instead of user@support.companyname.local
I have a red hat system that I currently have two websites hosted on. Im trying to set up a third domainname but every time I touch the files (httpd.conf, hosts, ddclient.conf, VirtualHosts,etc) it resolves to the primary domain name. The third domain keeps pulling up my first domain instead of resolving to its domain name. Any Ideas? I go through DynDns with custom domains. The first two have been working for years, but whenever I try to set up the third one exactly like the other two using the thirds info, it will not resolve to that third domain?????
i have installed SUSE 11 recently and have set the domain name and netmask using YaST settings after installation.But, the domain name is empty after rebooting. I have verified this using domainname command from terminal. But, in Network settings it is there.I think the system is not picking up the domain name from YaST settings.
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.
I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being user@mydomain.biz it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name. The Debian default
