dovecot - Dec 2018 - doveadm move and create folders for the archive

Hello guys,

I'm on a few mailinglists, which I want to archive at the end of the 
year. I know the command to do this, but must I create the folders for 
the archive by myself or is there a switch for doveadm? I tested this, 
but it exits with an error about the missing mailbox.

doveadm -D copy -u michael Archiv/debian-user/2018 mailbox debian-user since
365d

error message:

doveadm(michael): Debug: Effective uid=1000, gid=1000, home=/home/michael
doveadm(michael): Debug: Namespace inbox: type=private, prefix=, sep=,
inbox=yes, hidden=no, list=yes, subscriptions=yes
location=maildir:~/Maildir:LAYOUT=fs
doveadm(michael): Debug: fs: root=/home/michael/Maildir, index=, indexpvt=,
control=, inbox=/home/michael/Maildir, altdoveadm(michael): Error: Can't
open mailbox 'Archiv/debian-user/2018': Mailbox doesn't exist:
Archiv/debian-user/2018

Sorry for the long lines.

As the manpage for doveadm copy/move states: "The destination mailbox
must exist, otherwise this command will fail."

Is there some 'ace' here that is willing to offer support via skype or 
so related namespaces, locations and alias plugin? Won't be needing much 
time.

Thanks,
