there is no action in Sieve to specifically fail either, although there
is "reject".  sending a bounce to the sender is probably not what's
wanted, though.

I think it is better to change what Cyrus does with the folder Sieve
returns.  it would be nice if the action to take when the destination
folder is missing could be specified as one of:

  * return permanent failure
  * use INBOX (permanent failure if INBOX _is_ the destination)
  * create folder

actually, this could be done as a Sieve extension, too.
