Vom instala pachetul prin comanda de mai jos:

sudo apt install postfix

Pentru a configura postfix folosim comanda de mai jos:

sudo dpkg-reconfigure postfix
Pe ecran vor fi afisate optiunile de mai jos:

• Internet Site

• mail.example.com

• steve

• mail.example.com, localhost.localdomain, localhost

• No

• 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/24

• 0

• +

• all

Inlocuim mail.example.com cu domeniul nostru, 192.168.0.0/24 cu subnetul din care face parte server-ul de mail si steve cu usernam-ul dorit

Pentru configurarea format-ului de mailbox pentru Maildir folosim:

sudo postconf -e 'home_mailbox = Maildir/'

Va pune mail-urile noi in /home/username/Maildir

Configurare SASL:

sudo apt install dovecot-core

Se editeaza fisierul /etc/dovecot/conf.d/10-master.conf cu urmatoarele:

service auth {
  # auth_socket_path points to this userdb socket by default. It's typically
  # used by dovecot-lda, doveadm, possibly imap process, etc. Its default
  # permissions make it readable only by root, but you may need to relax these
  # permissions. Users that have access to this socket are able to get a list
  # of all usernames and get results of everyone's userdb lookups.
  unix_listener auth-userdb {
    #mode = 0600
    #user = 
    #group = 
  }

  # Postfix smtp-auth
  unix_listener /var/spool/postfix/private/auth {
    mode = 0660
    user = postfix
    group = postfix
  }

Pentru a permite clientilor Outlook sa foloseasca autentificarea SMTP-AUTH modificam linia din auth_mechanisms = plain in auth_mechanisms = plain login.

Restartam serviciul Dovecot:

sudo systemctl restart dovecot.service
