Hi,
(I'm not subscribed to the mailing list yet, please Cc me when replying; thank you!)
Based on the screenshots, Roundcube is excellent. I used IMP and Squirrelmail before, but I have to admit that they're not nearly comparable with Gmail or other modern webmails. Roundcube, though, seems to keep up with the best in the industry. It's like the iPod - it's not like there aren't any other similar products out there that are functional and stable, but this one is the only one whose interface actually makes sense from a usability perspective. ;-)
Kudos!
One issue that I'd like to discuss: I am using Cyrus IMAPd as a backend because it provides convenient and powerful server-side email filtering with Sieve (that is, I configure the filters on the server and then the messages are processed, deleted, sorted into folders, etc. automatically, server-side, regardless of what IMAP client I'm using - which is totally awesome). Both IMP and Squirrelmail provide nice integrated interfaces to manage the Sieve filters. E.g., see Avelsieve, which is the Squirrelmail Sieve plugin:

To me, Sieve filtering is what makes or breaks the deal. I would start to use Roundcube tomorrow if it had a Sieve interface. But if it lacks Sieve... well, I guess I won't use it "for real" because I would have a hard time setting up new filters or modifying existing ones, which is critical when you have more than, like, a dozen folders or so. Especially when subscribed to high-volume mailing lists (lkml, php-dev, etc.), automatically filtering messages into folders is critical and without server-side filtering it's impossible to use multiple IMAP clients (one could still get away with using just one single client and perform filtering client-side, but that pretty much precludes all the advantages of IMAP).
So... Is there any Sieve interface yet in Roundcube? If not, are there any plans to create one? If there are plans, what's the timeline?
Thank you, and kudos again for the excellent webmail interface.
