Setting Up An Email Server
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 [email protected]
