Vorraussetzung: postfix

/etc/dovecot/conf.d/10-mail.conf: ( Debian 8 )

mail_location = maildir:~/Maildir

service dovecot reload

doveconf mail_location

/etc/postfix/main.cf : ( Debian ab 5.0, openSuSE 12.1 )

home_mailbox = Maildir/
mailbox_command =

~/.muttrc

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

Debian (7): dovecot-lmtpd

( debian 8 )
auth_username_format ist essentiell, weil LMTP bei der Delivery nach diesem Verzeichnis sucht!

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

auth_username_format = %Ln

( openSuSE 12.1, debian 8 )

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

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

( openSUSE Leap 42.1, debian 8 )
Existiert noch kein ~./Maildir, schlägt die storage auto detection von dovecot fehl.

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

mail_location = maildir:~/Maildir

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