Thanks for asking, but I don't have enough free time currently for such 
a task.

I run postfix/dovecot on my VPS and have Sieve working with Dovecot. It 
wasn't that hard to configure. I have a sieve script I wrote that does 
very basic things (file mailing list emails into their own folders, mark 
certain emails as read automatically, etc), if there's interest I can 
post it. You're right, you can do really powerful stuff with Sieve, I 
just haven't had occasion to use it yet.

One cool thing I like about Sieve is the Managesieve [1] service, so a 
user can configure, edit, and check the syntax of sieve scripts without 
having to ssh into the mail server or anything. There's a fantastic
Thunderbird extension [2] that does this. Unfortunately, I'm more 
inclined to Mutt and I haven't yet found a good standalone ManageSieve 
client. But it's not like I need to update my sieve script that often,
