Hello cPanelers! I would like to use the RoundCube plugin "managesieve" to add filtering in my webmail. The thing is, I think that "managesieve" is not enabled/installed. It seem to come from the package "pigeonhole" from dovecot. I tried to install it with "yum" but I got the error "No package dovecot-pigeonhole available." So my question is.. what is the proper way to install/enable managesieve with cpanel? Thanks a lot!
