Hi Stephan, thank you for your work, I own you a beer!

I can wait a bit more for the cmusieve plugin to work next to managesieve
protocol, is there a bug report that I can subscribe to so I know when it
will work? Is it a planned feature for the next release? It was just a
bid unexpected that activating a users managesieve filter will break the
excising global cmusieve plugin.

Thanks in advance,
