First off, now that I'm running on DBMail 2225 let me say, THANK YOU!
I think the sieve functionality is a huge improvement for DBMail.
Now I've been tinkering and trying to get things going and have a few
comments.
We need better (more? some?) Sieve documentation. libSieve is hard to
install (running CentOS, probably easier on debian), and it's hard to
figure out how to use after you have it.
We need some example sieve scripts, a cook book page on the Wiki would
be a great improvement.
I just setup avelsieve for Squirrelmail, and it works pretty well. Very
easy to setup, and I don't have to learn to much about the actual sieve
functionality. We should mention avelsieve on the wiki somewhere, (and
possibly other sieve script generators if we deem them worthy).
