[gentoo-server] cyrus can't create mailbox

[Mauro Stettler]

hi together

i try to create a mailbox with cyradm. i got a system user "mst" and set
a password with saslpasswd2, but if i do "cm mst" in the cyradm-console,
i got the error createmailbox: Permission denied. I searched for any
files that are belong to cyrus and chowned them, but I don't know if I
missed some of them or that is another problem.

thanks for help

mauro
