Dovecot/en

Dovecot is a popular IMAP and POP3 server software.

Installation

 apt-get install dovecot-XXX 

XXX = the program which you wish to install

For example:

 apt-get install dovecot-imapd 

 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

Määritetään tunnistavat portit IMAP ja POP3 protokollalle.

service imap-login {
 inet_listener imap {
   port = 143
 }
 inet_listener imaps {
 #  port = 993
 #  ssl = yes
 }

service pop3-login {
 inet_listener pop3 {
   port = 110
 }
 inet_listener pop3s {
 # port = 995
 #  ssl = yes
 }
}

Define the smtp proofing 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

Jos otat käyttöön SSL suojatut yhteydet, määritä tänne SSL sertifikaatti ja ota SSL käyttöön

 ssl = yes

 ssl_cert = </etc/dovecot/dovecot.pem
 ssl_key = </etc/dovecot/private/dovecot.pem

Testaus

Voit testata telnet yhteydeää muodostaen yhteyttä palvelimeen, esimerkiksi

 telnet localhost 110

 telnet localhost 143

Kirjaudu esimerkiksi

 gg LOGIN [username] [password]

Siis korvaa [username] ja [password] omilla tunnuksillasi ja salasanaoillasi. Nämä ovat sama kuin Debianin kirjautumisen tunnukset.
