Well, MTP is Mail Transfer Agent. It is used as a mail server to transfer e-mails. This post will teach you basic installation of Postfix and its configuration. But let me tell you this well in advance, what I am going to teach you in this post is a very minimal configuration without any security and UI (I am leaving UI for my next post and security for you to Google!).
Now let us start with the installation. Install the Postfix by firing the following command:
Accept any dependencies, if presented. Now after the installation we need to configure it a little. On the terminal fire the following command:
sudo aptitude install postfix
You will see some options. Choose the most appropriate one, they are self explainatory. I will continue with the option "Internet Site" and follow the steps below.
sudo dpkg-reconfigure postfix
- Choose the system mail name. If you are setting up server for email@example.com then set the name as adityapatawari.com and hit OK
- Put a root recipient name or leave it blank if you want and hit OK
- Use this field to setup the server for other domains or your TLD.
- This option is used in case of system crash but you will not need it as you are using ex3 or ext4 file system having journaling capability and hit NO.
- Put up your local network. I use 127.0.0.0/8 and hit OK.
- Set the disk limit for the users. 0 stands for unlimited and hit OK.
- Use default at this screen and hit OK.
- Choose the Internet protocols you want and hit OK.
You can check it out by using the following command:
sudo /etc/init.d/postfix start
telnet localhost 25
There you go with your Postfix server. Now next post on WebMail UI.
