I just took a look at my fairly extensive sieve script that has been 
built by the managesieve plugin for the roundcube webmail server.  I 
don't often look at the script itself because that plugin lets me edit 
the script in a GUI.

The fileinto command is used in almost every one of my rules.  It is not 
copying the message, it is moving the message to the destination 
folder.  Here is one of my rules:

# rule:[blog]
if header :contains ["To","cc"] "blog at elyograg.org"
{
         fileinto "admin.blog";
         stop;
}

There is an extension to sieve that adds a :copy option to certain 
commands like fileinto for situations where that is actually what you 
want to do.  Pigeonhole does support it:
