We are moving from roundcube to SOGo. A lot of users have created filters which are saved as roundcube.sieve. This is the active sieve script.

When editing filters in sogo, sogo shows no filters. If I create a new filter, it is saved as sogo.sieve and deactivates the roundcuve.sieve.

The expected behaviour is to detect that there is an active sieve recipe and use it (show it in the editor and let the editor modify it).
