    Hello all,

    I try to set up a simple Dovecot instance on a raspberry where I can
    create one mailbox and use this for testing purposes with GNU Mailutils
    and ImapSync.

    Therefore I installed Dovecot out of the box and created a user ("cyrus").

    For now, it seems to run. While, only the non-encrypting protocols are
    used (no pop3s, no imaps):

    PORT STATE SERVICE
    22/tcp open ssh
    25/tcp open smtp
    80/tcp open http
    110/tcp open pop3
    119/tcp open nntp
    143/tcp open imap
    406/tcp open imsp
    631/tcp open ipp
    8008/tcp open http

    When I try to log into Dovecot, it asks for password (based on /etc/shadow
    as it looks like), but then Dovecot asks for some imap password:

    [502 root@rpi-inst ~]# cyradm -u cyrus localhost
    Password:
    IMAP Password:
    Login failed: authentication failure at /usr/lib/arm-linux- gnueabihf/perl5/5.32/Cyrus/IMAP/Admin.pm line 134.
    cyradm: cannot authenticate to server as cyrus

    Can anyone please give some advice how to get a mailbox set up, so that I
    can test with?

    Thank you!
