[Dovecot] doveadm altmove -r

Hi there,

there is the ubuntu version 2.0.13 ov dovecot installed on our server. But in contrast to http://wiki2.dovecot.org/Tools/Doveadm/Altmove the option -r isn't supported in this version.

altmove: invalid option -- 'r' doveadm altmove [-u <user>|-A] [-S <socket_path>] <search query>

In which version of dovecot is this option supported?

Thanks Lars
