doveadm mailbox cryptokey - not found

Hi, we have a problem. Command "doveadm mailbox cryptokey" does not work:

# doveadm mailbox cryptokey usage: doveadm [-Dv] [-f <formatter>] mailbox <command> [<args>] create [-u <user>|-A] [-S ] [-s] [-g <guid>] <mailbox> [...] delete [-u <user>|-A] [-S ] [-e] [-r] [-s] [-Z] <mailbox> [...] ......

What is the problem?
