I don't want the user to have control over the spam sieve filter, because other systems depend on the location where spam is archived. As a workaround, one may think it is possible to have your global x-spam-flag.sieve include the user's sieve script with the include extension. This will work, however, the CMUSieve plugin requires any included Sieve script to exist. A nasty side effect of this is that any user who deactivates his Sieve script through ManageSieve ends up deleting the link to it on the server. This will break the include from the global Sieve script and end its execution. I am not sure whether there is a proper workaround to achieve something like this for Dovecot versions prior to v1.2. Can't think of any... Regards, Stephan

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, Jelle de Jong

Hehe, looks like we share a country, so I may take you up on that offer :) 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. Well, the main problem is not that CMUSieve and ManageSieve don't work together. Keep in mind that ManageSieve uses the CMUSieve plugin to perform the actual execution of the script, so these are not conflicting in any way. Rather, CMUSieve does not support executing the global Sieve script and the personal user script sequentially: currently these are mutually exclusive. The new Sieve plugin for Dovecot v1.2 supports this using the sieve_before setting: http://hg.rename-it.nl/dovecot-libsieve/file/tip/INSTALL So, for Dovecot v1.2 this is already fixed (still needs to be tested more though). Implementing this for Dovecot v1.0/v1.1 with CMUSieve requires significant changes and I don't think it is worth doing so, because CMUSieve is being replaced with the new implementation for Dovecot v1.2. Therefore, I think 'waiting' will mean waiting until you are prepared to use v1.2 (e.g. when it is deemed to be stable). Regards, Stephan Bosch
