Long Term Read Only Archive with Kolab?

[Karma Kolabor]

Hi,

another one: is it possible to realize a read-only archiving solution
with Kolab?

Usually I do such kind of thing with sending copies of all emails to
another imap server that is configured for login only for several
users, however a more integrated solution would be great.

Does there exist some archiving solution for kolab yet?

Thanks again,
Karma
