Vorraussetzung:

• dovecot
• postfix

Mails im Maildir-Format speichern: ¹⁾

/etc/dovecot/conf.d/10-mail.conf

…
mail_location = maildir:~/Maildir
…

doveconf mail_location

siehe oben

/etc/postfix/main.cf

…
home_mailbox = Maildir/
mailbox_command =
…

postconf home_mailbox
postconf mailbox_command

~/.muttrc

set mbox_type=Maildir
set folder="~/Maildir/"
set mbox="~/Maildir/"
set spoolfile="~/Maildir/"

Debian (ab 7): dovecot-lmtpd

Debian (ab 8):

/etc/dovecot/conf.d/10-auth.conf

…
auth_username_format = %Ln
…

²⁾

doveconf auth_username_format

openSuSE 12.1, debian (ab 8):

/etc/dovecot/conf.d/10-master.conf

…
service lmtp {
  unix_listener /var/spool/postfix/private/dovecot-lmtp {
    user = postfix
    group = postfix
    mode = 0660
  }
…
}

Konfiguration prüfen:

doveconf protocols
doveconf -n

Dienst neu starten:

systemctl restart dovecot.service

Prüfen, ob dovecot den Socket angelegt hat:

ls -l /var/spool/postfix/private/dovecot-lmtp

postconf -e 'mailbox_transport = lmtp:unix:private/dovecot-lmtp'

Zu Testzwecken das eigene Netz als mynetworks eintragen, also statt /32 ein /24

postconf mynetworks
mynetworks='127.0.0.1/32 192.168.225.102/32 [::1]/128 [fe80::5054:ff:fe00:102]/12'
postconf mynetworks='127.0.0.1/32 192.168.225.0/24 [::1]/128 [fe80::5054:ff:fe00:102]/12'
