Ok, I've found this option to be introduce in version 2.0.14. Maybe someone (with the permissions) should add this info to the wiki page.

Best wishes Lars

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
