Zimbra Collaboration Server - known product of VMWare, which represents not only the level of corporate e-mail, but calendar and collaboration tool, equally suitable for both large companies and small firms. In this article we will look at setting up an Open Source version of Zimbra on a server running Ubuntu 12.04 LTS.
And why are all the same Zimbra? There are several reasons. First post just as a means to send - receive electronic correspondence today few people happy. At a minimum, with the ability to send calendar tasks and monitor their progress. It is also highly desirable to have a user-friendly titlovi web-based interface that supports the operation of mobile devices for employees outside the office. And this - the minimum necessary. Today, even the free email services can offer a lot of these. Regular readers will recall that at the time we started a series dedicated mail server for beginners, but with the practical part came out very long delay. We tried several times to prepare materials and convinced titlovi that "classical scheme": Postfix (Exim) + Dovecot is very complicated to configure titlovi beginners and less complicated titlovi administration of the bunch. And put a bullet in this scheme that receives the output product is suited for a maximum of email hosting and corporate environments turned out useless. At the same time Zimbra even in the free version provides all that is necessary to corporate clients and is very easy to install and use. For installation, we will use a server running Ubuntu Server titlovi 12.04 64-bit and assumes that the reader has basic skills administer Linux, and has the necessary minimum of knowledge, even if the amount of these materials: Mail server for beginners. Structure and operation. Mail server for beginners. Configuring DNS zone. Before attempting to set up a mail server, you should ensure that the domain is made MX-record titlovi that points to the mail host A record which contains the external IP-address of your corporate network. In this case, the host name of the mail and will mail.interface31.ru A record of this host will point to the external interface of our router, mail server itself will be located in the local network and have the address 10.0.0.25. When installing the system titlovi should pay attention to two features: Mail server name should be the full FQDN hostname, eg in our case mail.interface31.ru. Since Zimbra itself and all messages are stored in / opt, it makes sense to put it on a separate disk. After installing the update the system titlovi and initiate the preparatory work. Obligatory condition of normal operation Zimbra - your DNS server must contain MX and A records for the host. In the case where the mail server is on a LAN behind a NAT setting scheme requires double horizon DNS (Split DNS), it can be configured on the DNS server enterprise that requires titlovi a fairly deep knowledge used DNS-server or installed on a host with Zimbra DNS-server - stub, which will have the necessary records and serve only the mail server. For these purposes, establish dnsmasq apt-get install dnsmasq and give it a config / etc / dnsmasq.conf to the following form: server = 10.0.0.1 domain = interface31.ru mx-host = interface31.ru, mail.interface31.ru, 10 listen -address titlovi = 127.0.0.1 titlovi The first option specifies the parent DNS-server, as is used, you must specify your DNS network or one of the public servers. Now should correct / etc / hosts to contain the following titlovi entries: 127.0.0.1 localhost.localdomain titlovi localhost 10.0.0.25 mail.interface31.ru mail Then configure our server to use a local DNS, we should remember that in Ubuntu 12.04 resolv.conf generated automatically and to specify the DNS-servers, you should use the file / etc / network / interfaces, which in this case has the following contents: auto eth0 iface eth0 inet static address 10.0.0.25 netmask 255.255.255.0 gateway 10.0.0.1 dns-search interface31.ru dns -nameservers 127.0.0.1 titlovi Save the configuration, restart the server. To verify the settings, the command: dig interface31.ru mx which should return as the MX-record the name of our server, an A record to point to the local address. Install the necessary dependencies: apt-get install libgmp3c2 apt-get install libperl5.14 apt-get install sysstat apt-get install sqlite3 on this server training is finished, you can go directly to install Zimbra. Download the package from the developer's site and place a file on the server, for example in the home folder. Then move in and unpack the archive to enter long names convenient type the first few letters and use autocompletion on Tab: cd ~ tar xzvf zcs-8.0.1_GA_5438.UBUNTU12_64.20121105164409.tgz Now go to the unpacked folder and run the screening
