Sisällysluettelo
Installation
Install the Dovecot features that you want
apt-get install dovecot-XXX
XXX = the program which you wish to install
For example:
Asenna IMAP protokola (suositus)
apt-get install dovecot-imapd
Asenna POP3 protokola (ei suositella)
apt-get install dovecot-pop3d
Configuration
The Dovecot configuration directory is located in
/etc/dovecot
After installing dovecot it is recommended to open the file and save it with another name, for instance XXX.conf.save, since the original configuration file is good to have as backup and reference.
According to the default configuration we use the configuration files located in /etc/dovecot/conf.d/ . If you want to, you can make the configurations directly into /etc/dovecot/dovecot.conf .
conf.d/10-auth.conf
In the bottom end of the file you will find links to other configuration files for logging in. We use the system login info.
#!include auth-deny.conf.ext #!include auth-master.conf.ext !include auth-system.conf.ext #!include auth-sql.conf.ext #!include auth-ldap.conf.ext #!include auth-passwdfile.conf.ext #!include auth-checkpassword.conf.ext #!include auth-vpopmail.conf.ext #!include auth-static.conf.ext
conf.d/10-mail.conf
In this file we define the mailbox location.
mail_location = mbox:~/mail:INBOX=/var/mail/%u
Allow removing e-mail in Dovecot:
mail_privileged_group = mail
conf.d/10-master.conf
Otetaan käyttöön IMAP protokolle portit (Asenna dovecot-imapd jos ei ole asennettu):
service imap-login { inet_listener imap { port = 143 } inet_listener imaps { # port = 993 # ssl = yes }
Otetaan käyttöön POP3 protokolalle portit (Asenna dovecot-pop3d jos ei ole asennettu):
service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { # port = 995 # ssl = yes } }
Define the smtp authorizing on the server.
service auth { ... # Postfix smtp-auth unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix }
conf.d/10-ssl.conf
If you enable SSL secured connections, you should define the SSL certificate and enable SSL here.
ssl = yes
ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem

Testing
You can test making a telnet connection to the server, for example
telnet localhost 110
telnet localhost 143
Login for example
gg LOGIN [username] [password]
In other words, replace [username] and [password] with your own credentials. They are the same as Debian login credentials.
