Setting Up An Email Server

March 12, 2013   

Exim4

Exim4 is used for setting up a SMTP mail server.
It is installed by default in Ubuntu Server. You need to reconfigure it to be used.

Install:

sudo aptitude install exim4

Reconfigure Exim4:

sudo dpkg-reconfigure exim4-config

Set all settings as default except the domain name. Type a correct domain name, that is alive.

Postfix:

It is recommended to use postfix

sudo apt-get install postfix

On Mac:

postfix is already installed by default.

sudo vi /System/Library/LaunchDaemons/org.postfix.master.plist

add following line before the closing </dict> tag:

<key>RunAtLoad</key>
<true/>
<key>KeepAlive</key>
<true/>

Start service

sudo postfix start

Check that SMPT is running:

telnet localhost 25

Test Email:

date | sendmail username@domain.com
