Re: Question: Actual "stable" james-server-app-3.6.1-app.zip and managesieve with starttls: ClassCastException ChannelManageSieveResponseWriter

[Benoit TELLIER <bt...@apache.org>]

Hello Gatherer,

ManageSieve is known-to-be-buggy for quitte some time.

I recently had a look at it [1] [2] and made it work with the
Thunderbird plugin. The status of this work is still experimental though...

This fix is available on master and on the (hopefully) upcoming 3.7.0
however I must confess I did not bother backporting the fixes on the
3.6.x branch.

Best regards,

Benoit
