Introduction

In this article, we will explore the process of setting up a home server on Fedora with Dovecot and Postfix to manage emails. We will also discuss how to retrieve emails from a standard email account online (Libero.it) to our local server using Getmail6. This setup will allow us to manage our emails locally and access them from anywhere using our local server.

Setting Up Dovecot and Postfix on Fedora

To set up Dovecot and Postfix on Fedora, we need to install the necessary packages. We can do this by running the following command in the terminal:

sudo dnf install dovecot postfix

Once the installation is complete, we need to configure Dovecot and Postfix. We can do this by editing the configuration files.

Configuring Dovecot

To configure Dovecot, we need to edit the /etc/dovecot/dovecot.conf file. We can do this by running the following command:

sudo nano /etc/dovecot/dovecot.conf

In this file, we need to set the mail_location option to /var/mail/vhosts/%d/%n and the mail_home option to /var/mail/vhosts/%d/%n. We also need to set the auth_mechanisms option to PLAIN PLAIN-CLIENTRESPONSE. Here is an example of what the configuration file should look like:

mail_location = /var/mail/vhosts/%d/%n
mail_home = /var/mail/vhosts/%d/%n
auth_mechanisms = PLAIN PLAIN-CLIENTRESPONSE

Configuring Postfix

To configure Postfix, we need to edit the /etc/postfix/main.cf file. We can do this by running the following command:

sudo nano /etc/postfix/main.cf

In this file, we need to set the message_size_limit option to 10485760 and the message_body_size_limit option to 10485760. We also need to set the virtual_alias_maps option to hash:/etc/postfix/virtual. Here is an example of what the configuration file should look like:

message_size_limit = 10485760
message_body_size_limit = 10485760
virtual_alias_maps = hash:/etc/postfix/virtual

Creating a Virtual Alias Map

To create a virtual alias map, we need to create a file called /etc/postfix/virtual. We can do this by running the following command:

sudo nano /etc/postfix/virtual

In this file, we need to add the following lines:

@libero.it  user@localhost

This will map the @libero.it domain to the user@localhost address.

Starting Dovecot and Postfix

To start Dovecot and Postfix, we need to run the following commands:

sudo systemctl start dovecot
sudo systemctl start postfix

Retrieving Emails with Getmail6

To retrieve emails with Getmail6, we need to install the package. We can do this by running the following command:

sudo dnf install getmail6

Once the installation is complete, we need to configure Getmail6. We can do this by editing the /etc/getmail/getmail.conf file. We can do this by running the following command:

sudo nano /etc/getmail/getmail.conf

In this file, we need to set the retrievalmethod option to POP3 and the pop3server option to pop3.libero.it. We also need to set the username option to our email address and the password option to our email password. Here is an example of what the configuration file should look like:

retrievalmethod = POP3
pop3server = pop3.libero.it
username = user@libero.it
password = password

We also need to set the destination option to the path where we want to save the emails. We can do this by setting the destination option to /var/mail/vhosts/%d/%n. Here is an example of what the configuration file should look like:

destination = /var/mail/vhosts/%d/%n

Starting Getmail6

To start Getmail6, we need to run the following command:

sudo systemctl start getmail6

Testing the Setup

To test the setup, we can use the mail command to send an email to our local server. We can do this by running the following command:

sudo mail -v user@localhost

This will send an email to our local server. We can then use the getmail6 command to retrieve the email. We can do this by running the following command:

sudo getmail6

This will retrieve the email and save it to the /var/mail/vhosts/%d/%n directory.
