Yes, cyrus is listed as admin in imapd.conf on the backend. The logs on the
backend do not show anything, I think that the frontend can not connect to
the backend. However I can connect to the backend from the frontend with
imtest.

Meanwhile I saw that Arnaud at opensquad.com posted the same question in
April this year here. He could not solve the problem and switched to another
version. Probably this package has a bug.
