Sieve does not support includes.

I use the 'sievetest' program which comes with cyrus.  It will identify 
parse errors, but I'm not sure how sophisticated it is in general.

Sieve does not stop processing when it reaches a match.  Your Sieve logic 
must specifically tell it to stop, or be structured in such a way so that 
multiple matches do not occur (if that is your intention).

A good example is one email message sent to multiple mailing lists.  I 
filter each mailing list into a separate folder.  Some people would like 
to receive the message in each folder (multiple matches).  Others might 
like to receive only one copy of the message.  Use of if, elsif, else 
logic can provide both options, depending on your preference.
