How to use sieves?

[David Wu]

Hi guys,

I am kind of new to cyrus... or MDA in that sense. I read that one can 
use sieves in cyrus to create vacation auto-reply kind of actions. I 
read the syntax of sieves and so on. But how do I get started? Do i 
have to install sieves? or its compiled as part of cyrus?. I am using 
the default cyrus came with Mac OS X 1.3 (Panther).
If it is compiled in it , how do i write the script and install it? or 
where do i put it so cyrus would read it?

Thanks Lots
David
