Thanks for the suggestion. We do that as well, specifically for system-wide spam filtering into a spam folder. In fact, our users can also use the Thunderbird Sieve extension to maintain their own personal sieve scripts for additional filtering.
For those users that we wish to convert over to using Sogo as their primary mail interface, we would like to offer the same feature set as for those that use Thunderbird. In fact, if you cannot successfully activate Sieve for individual use, how can you use the "Vacation" and "Forwarding" features of Sogo? Am I missing something? --Firedup -- users@sogo.nu https://inverse.ca/sogo/lists
