Blindly following things you find on the Internet is not a path to 
success. :)

You may consider whether your own depth of understanding is sufficient 
to improve the situation, or whether you are simply adding more noise. I 
wish you luck in any case.

We all have our own areas of expertise. Nothing wrong with that.

Not precisely. You want to remove the 'else' in there, as the clause you 
have will do the opposite of what you intend. Also note that I removed 
your superfluous square brackets.

The best way to work with this is to start with simple rules on an 
individual client. Once you get a rule set that works, then you can move 
on to compiling it for the system. Always start as simple as possible 
though, and only add to it if your simple thing does not work.

This is a pretty good tutorial on the syntax and options for Sieve. 
Given your intended purpose you should pay special attention to the 
'create' modifier for 'fileinto'. Also, I would accomplish both things 
in the same rule using 'anyof' which should be slightly more efficient 
(which could make a big difference to server load depending on how many 
users you are supporting).
