Subject: Dovecot for testing - can someone please give advice?./. Was: Citadel? Courier? Cyrus? Dovecot? - I just want to backup my emails

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!
